# Last Friday Night (T.G.I.F.)

"Last Friday Night (T.G.I.F.)" is a song by American singer Katy Perry from her third studio album, Teenage Dream. The song was produced by Dr. Luke and Max Martin, who also co-wrote the song with Perry and Bonnie McKee. Perry stated that she was inspired to write the track after a night of wild partying and streaking. It was released as the album's fifth single on June 6, 2011, by Capitol Records, with a remix featuring American rapper Missy Elliott released to US radio stations and digital retailers on August 8, 2011; this version was included in Teenage Dream: The Complete Confection edition. It is a dance-pop song with lyrics about drunken fun and debauchery. Some of the risqué lyrics are often censored in radio versions of the song.
The song had chart success worldwide, reaching number one in Canada, Slovakia and the Czech Republic, and has attained top-ten positions in Austria, Ireland, Italy, and Poland. When it topped the US Billboard Hot 100, Perry became the first female solo artist to have five number-one singles on the Hot 100 from a single album; it also was Perry's sixth number-one single on the Billboard Hot 100 chart, and her fifth consecutive number one single. The single has sold 3.8 million digital copies in the US and was the tenth most played single on US radio during 2011.
The song's accompanying music video was directed by Marc Klasfeld. The clip features Perry, as her teenage alter-ego Kathy Beth Terry, at a house party filled with music and dancing. While at the party, Terry is made over by her friend and draws attention to herself as the life of the party. Rebecca Black, Corey Feldman, Debbie Gibson, Kenny G, Hanson, Kevin McHale, and Darren Criss all appear in the video. According to the director, the inspiration behind the video was Sixteen Candles, works by American filmmaker John Hughes, and other 1980s high school films. The music video won Favorite Music Video award at the 38th People's Choice Awards.

## Background and artwork

Perry has revealed that she was inspired to write the track after running naked through a park with her friends. According to Music Rooms, Perry claims that after a wild night of partying and streaking, she wrote the song about her antics and what she remembered the next day. Perry revealed: "There's nothing better than an impromptu dance party with my friends. My track 'Last Friday Night (T.G.I.F.)' is a song about debauchery because I had one of those nights in Santa Barbara. We went out to this place called Wildcat and got crazy," Perry admitted: "We had a couple of beers and danced until we died, then brought the party back to the hotel room." She added: "Most of that song is actual truth, apart from the ménage à trois..... unfortunately! But, yes, streaking in the park, that's what we did, so we had to write a song about it the next day!"
One of the friends in this trip was co-writer Bonnie McKee, who said the song encapsulated "Katy and my wild drinking days" from their younger days. McKee stated "TGIF is pretty much a word for word description of our trip to Santa Barbara, so I love that one. It's really catchy and fun and makes me nostalgic." The official artwork for "Last Friday Night (T.G.I.F.)" using scenes from the music video, shows Perry both before and after a makeover. She revealed the cover artwork for "Last Friday Night (T.G.I.F.) Remixes!" on her Facebook page. The photo features Perry in nerdy gear, including mouth guard and glasses, and was taken when she hosted the Teen Choice Awards in summer 2010. The image is surrounded by 1980s-style neon colors and swirly graphics. A remixed version of "Last Friday Night (T.G.I.F.)", featuring Missy Elliott, was released on August 8, 2011, to radio and as a digital download. It was released as the album's fifth single on June 6, 2011, through Capitol Records.

"Last Friday Night (T.G.I.F.)" is a dance-pop and new wave song, with elements of indie rock, which runs for three minutes and 50 seconds. It is set in common time and has a moderate tempo of 126 beats per minute.

## Critical reception

AllMusic picked it among the top tracks on the album, and said that Perry "salutes fellow attention-whore Kesha on 'Last Friday Night (T.G.I.F.)'". Rolling Stone said that "Perry likes her songs chatty; in the kegger romp "Last Friday Night," she chirps, "Think I need a ginger ale/That was such an epic fail". Slant Magazine said that "'Last Friday Night (T.G.I.F.)' is a lifeless roller-rink jam with a 'T! G! I! F!' shout-along that will no doubt provide the soundtrack to any number of trashy sorority parties this semester". Spin Magazine said that "Last Friday Night recounts an evening of nonstop naughtiness – think streaking, skinny-dipping, and ménage à trois-ing."
Jason Richards from Now wrote, "The singer recently said that the catchy 'Last Friday Night (T.G.I.F.)' is her version of 'I Gotta Feeling'. With lyrics about photos ending up online after a debauched evening, it's also reminiscent of Lady Gaga singing about drunkenly losing her keys and phone on 'Just Dance.' Derivative, sure, but the song strikes a perfect equilibrium between Perry's sex appeal and goofy, self-effacing charm". Marc Hawthorne from The A.V. Club said that "assuming that everything here is based on real life also means we have to accept that she's had a ménage à trois on the indie-rock-meets-American Idol cut Last Friday Night (T.G.I.F.)".
Chris Richards from The Washington Post said that "Over strummy guitars and zigzagging keyboards, Perry recounts an evening of debauchery with no repercussions, her innocent transgressions (streaking, skinny-dipping) mentioned in the same breath as more serious trouble (mysterious bruises, a blackout), but..... [when] it's time for Perry to reflect on her 3 am follies, she stiffly sings, "That was such an epic fail." It sounds like a clueless parent's attempt to speak teenager." Billboard included the song in their Five Potential Pop Hits for 2011 list. Tom Hawthorne from Future Music Charts said that it sounds like a pop song as it should be without any auto-tune voice changes and hard DJ beats, which is the song's strength and weakness at the same time".

## Chart performance

"Last Friday Night (T.G.I.F.)" made Perry the first and only female artist to have five number one singles from one album in the Billboard Hot 100, tying Michael Jackson's Bad, with his last number one single being "Dirty Diana", on July 2, 1988. Perry's song debuted at number 67 on the Billboard Hot 100. It also charted at number 49 on the Canadian Hot 100 chart that same week.

The following week, the song jumped 63–31 with the Hot 100's "Greatest Gainer" award. In its fourth week on the chart, "Friday" leaped to number four, spurred by a number one ranking on Hot Digital Songs.

The following week, "Last Friday Night (T.G.I.F.)", reached a new position of number two, where it remained for three additional weeks, behind "Party Rock Anthem" by LMFAO feat.

## Music video
### Background and release

In an interview with MTV, director Marc Klasfeld said that the video's storyline was inspired by Sixteen Candles and other works of John Hughes, as well as "all those great '80s high school movies." Including a long series of outtakes during the ending credits was influenced by a similar idea in The Cannonball Run. The costume for Perry's character, Kathy Beth Terry, was inspired by the character Betty Suarez, played by America Ferrera on the series Ugly Betty. The music video for "Last Friday Night (T.G.I.F.)" was filmed around May 3–6, 2011 at the home of John Schneider. It was directed by Marc Klasfeld, and co-directed by Danny Lockwood. Perry tweeted, "I told someone about my new music video I just filmed & they responded with 'wow, that's gonna break the internet.'..... Should I knock on wood?"
Before the video premiered, Perry created Facebook and Twitter profiles for a "brace-faced nerd-turned-hottie" thirteen-year-old she plays named Kathy Beth Terry. Starting from June 8, a series of short video clips was uploaded on the Facebook profile, YouTube and Perry's official web version premiered later on the same day on Funny or Die. On July 11, after crossing the half-million "likes" mark, Perry released an interview in character as Terry on Digital Spy. Perry, in character as Kathy Beth Terry made various references to Rebecca Black and other guests on the video on her Twitter and Facebook. She also gave interviews to the Digital Spy, Australian Cosmopolitan, and BOP Tiger Beat.
The video went on to win Favorite Music Video award at the 38th People's Choice Awards.

### Synopsis

"Kathy Beth Terry" (Perry), a teenager with braces, headgear, and oversized glasses, has just awakened the morning after a house party, surrounded by passed-out partygoers. A male guest, Aaron Christopherson (Glee star Darren Criss) opens the door to her bedroom and congratulates her on having the "best party ever." Puzzled as to what happened, she goes online, only to find pictures of herself in various compromising positions, including one picture of her licking the stomach of the boy in bed next to her. The video then goes into a flashback of the events that occurred the night before. While doing a Sudoku puzzle, Kathy hears loud music from the house next door, and goes over to complain. She is greeted by Rebecca Black (who appears as a homage to Black's viral video "Friday"), who invites her in. Everett McDonald (portrayed by Glee star Kevin McHale) ogles Kathy from afar and fantasizes about being with her.
However, Kathy is more interested in football player Steve Johnson (model Richie Nuzzolese), who turns her down because of her appearance and appears more interested in a blonde (Angela Frezza). To cheer her up, Black gives Kathy a makeover, ripping off her headgear with pliers, waxing her upper lip, dressing her in tight-fitting neon clothes, and teasing her hair out. Steve becomes enamored with her, and everyone starts dancing. Kathy and Rebecca are also seen playing a Just Dance dancing video game (a series that features songs by Perry), in this case, dancing to "Hot Stuff" by Donna Summer from Just Dance 2). In the backyard, pop-rock band Hanson acts as the house band while Kathy's uncle Kenny (musician Kenny G) appears and plays the saxophone solo on the roof of the house (done in a mimed performance, as he did not play the instrument in the actual recording). The entire party ends up moving to Kathy's house, where she throws up after drinking too much. Everett punches the football player for grabbing Kathy's buttocks (visualized by him as a medieval sword fight with Kathy as a damsel in distress).
At the end of the night, Kathy finally passes out next to the football player. The video shifts back to the next morning, where she looks at the photos with regret, but is also ecstatic to have a naked football player sleeping in her bed. The film ends with Corey Feldman and Debbie Gibson as Kathy's parents, Kirk and Tiffany Terry, confronting Kathy about the state of the house after hearing about uncle Kenny playing the saxophone, but forgiving her after recalling their own wild youth. The video's ending credits feature various deleted lines, bloopers, and extra scenes from the party, as well as Everett bringing Kathy breakfast in bed. After the credits end, it repeats the shot where Kathy gets tape ripped off her upper lip, but her scream is heard this time.

## Live performances

On September 5, 2010, Perry performed the song live for the first time along with "Teenage Dream", "Firework" and "Not Like the Movies" in the show's launch of the Teenage Dream in Berlin. Though the song has never been performed live as part of a televised performance, the song is featured on the set lists of the California Dreams Tour, Prismatic World Tour, Witness: The Tour and her residency Play. The first televised performance was during her presentation at Rock In Rio, which was broadcast live by the Multishow. During this song, photos of fans are displayed on the screens.
