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). The band Hanson acts as the house band. In the climax Kathy's uncle Kenny (musician Kenny G) appears and plays the saxophone solo on the roof of the house 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. McHale's character 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 McHale's character 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 Teenage Dream Tour, California Dreams Tour, Prismatic World Tour and Witness: The Tour. 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.
