Document 2: Stefon: Stefon's segments were inspired by real people Hader and Mulaney had encountered, including an email Mulaney had received recommending parties and other points of interest to him, and a barista at a coffee shop that Hader met who looked and talked like Stefon. Mulaney decided that Stefon should wear an Ed Hardy shirt, under the assumption that it was made of latex and looked like something out of the Macaulay Culkin and Seth Green film, Party Monster. Stefon's hair was inspired by the characters in that film, ``specifically based in popup club culture in New York City circa 2007 ''. Stefon's last regular appearance on SNL was on May 18, 2013, owing to Bill Hader's leaving the show. As part of the Weekend Update comedy skit, Seth Meyers realized how much he actually loved Stefon and`` married'' him.

Document 14: Bodyshockers: Bodyshockers (also known from the second series onwards as Bodyshockers: Nips, Tucks and Tattoos) is a Channel 4 documentary series fronted by Andover-born presenter, author, philanthropist and acid attack survivor Katie Piper. The programme meets people from across the United Kingdom who either regret past cosmetic surgery or body art procedures and wish these to be reversed, or who are planning to undergo such procedures, often for the first time: in each edition, one of those planning to undergo the modification will meet with one of those who plans reversal of similar work, in order to discuss the potential pitfalls of said surgery. "Bodyshockers" first aired in early 2014; a second series followed in 2015 and a third season began airing in January 2016. The program is the first of Katie Piper's Channel 4 projects to be reordered beyond its initial run.
Document 15: Hard Rock Cafe: The chain began to expand worldwide in 1982 with locations in (among others) Toronto, Los Angeles, San Francisco, Chicago, Paris, and Berlin. Hard Rock Cafe locations in the United States vary from smaller, more tourist driven markets (Biloxi, Pigeon Forge, Key West, etc.) to large metropolises (Houston, Philadelphia, New York City, Chicago, Boston, Washington, D.C., etc.). Hard Rock Cafe typically does not franchise cafe locations in the United States. All US cafes are corporate owned and operated, except for cafes in Tampa and Four Winds New Buffalo casino. However, in the transition of the Las Vegas Hard Rock Hotel property originally owned and then later sold to Rank by founder Peter Morton, Morton retained hotel naming rights west of the Mississippi. When Morton sold his Las Vegas Hard Rock Hotel to the Morgans Hotel Group, he also sold those naming rights, which then gave rise to two US franchised hotels (without cafes) in Albuquerque and Tulsa. The Albuquerque hotel no longer pays for the Hard Rock rights and reverted to its former name in June 2013. More hotels franchised from Morgan's are planned for Sioux City and Vancouver.
