Another minor spoiler from the Book of Mormon, and this submission - the scene including the song TURN IT OFF.
I about died laughing when they clapped their hands in unison and the house lights went off. Second time, when they came back up and they were wearing pink sequined vests and chorus-line danced. Imagine that your brain is made of tiny boxes, find the box that’s gay and CRUSH IT!
Tootsie's restaurant scene killed me, which is arguably emblematic of the show as a whole because I don't think that that scene actually has a song in it, but god it was funny.
