Waiting...

The film focuses on several characters. One of the main protagonists, Dean (Justin Long), has been a waiter at a restaurant called Shenaniganz for four years since graduating from high school, and has not earned a degree during his four years at a community college. When Dean learns from his mother that a former high school classmate, Chett (Travis Resor), now has a bachelor's degree in electrical engineering, he begins to rethink his direction-less life. Dean's friend and co-worker, Monty (Ryan Reynolds), is in exactly the same situation, but has accepted that his future lies with the restaurant. Monty is put in charge of training Mitch (John Francis Daley), a newly hired waiter who is constantly interrupted throughout most of the film before he can speak, usually by Monty. Also working with Dean is Calvin (Robert Patrick Benedict), a hopeless romantic who cannot urinate in public, and Dan (David Koechner), the uptight manager who is grooming Dean as his protÃ©gÃ©. Rounding out the staff are 17-year-old hostess Natasha (Vanessa Lengies), abrasive waitress Naomi (Alanna Ubach), waitress (and Monty's ex-girlfriend) Serena (Anna Faris), Dean's girlfriend and fellow waitress Amy (Kaitlin Doubleday), stoner busboys T-Dog and Nick (Max Kasch and Andy Milonakis), head chef Raddamus (Luis Guzman), the insane, unsanitary chef Floyd (Dane Cook), lesbian bartender Tyla (Emmanuelle Chriqui), and the pensive and philosophical dishwasher Bishop (Chi McBride).
The waiters preoccupy themselves with endless gossip, complaining about the customers, seeking covert revenge on particularly rude or annoying patrons, and playing a special kind of game which involves flashing genitalia at a fellow worker (the "Penis Showing Game"). Each employee has his or her own problems and stories, which are interwoven with the ebb and flow of business. A common phrase used throughout the film, which is referred to in the Shenaniganz training video is "The only thing different between extraordinary and ordinary, is that little bit of extra!" This phrase is mocked by many of the wait staff during the film.
Minutes before the restaurant closes, however, Chett and his girlfriend come in for dinner and leave Dean a hefty tip out of pity. This prompts Dean to quit his jobâturning down an assistant manager position Dan offered him at the beginning of the filmâto seek a more promising future.
When the shift ends, the staff head to a party at Monty and Dean's house. At the party, Monty - who has a predilection for sleeping with teenage girls - is able to resist having sex with Natasha, although he says they will have sex the following Wednesday, when she will be 18. Calvin attempts to fix his relationship problems, and Mitch finally speaks, calling out his coworkers on their problems and quitting. He concludes by giving them all The Goat from the "Penis Showing Game", which Raddimus had told him earlier would instantly grant him god-status. Sure enough, Monty swears his undying allegiance to Mitch, telling Dean he's been "replaced." The film ends with the staff talking about the incident with Mitch, and Dan showing up at a disgruntled customer's house after Natasha gave him the wrong address to the party.
