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!"[1] 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.[2] 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."[3] 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.[4] A remixed version of "Last Friday Night (T.G.I.F.)", featuring Missy Elliott, was released on August 8, 2011 to radio and digital downloads.[5][6] It was released as the album's fifth single on June 6, 2011 through Capitol Records.[7]
