Glee travels back in time for an episode that was allegedly "too controversial" to air . . . 

Kevin feels the episode should have stayed unaired, even though some of Jenna's scenes made him laugh out loud! Jenna shares her not-so-fond memories of this episode, including the dress that gave her scabs under her arms, Kevin's itchy fake mustache that made him lose it, the scene where Jenna clearly didn't know the dance moves, and the moment they felt they hit rock bottom!
