Richmond says he and Fey trust each other to tell the other when something isn't working or when something will certainly work. He remembers a moment of doubt in Mean Girls. Fey had in the script a moment where Regina is cheating on Aaron with the school's hot mascot Shane Oman in a lion mascot suit -- quite literally. The gag is that the actor playing Shane comes out on stage with an extra person hidden in the suit with him during the montage-like song "Revenge Party," in which Cady and Janis plot Regina's destruction. Suggestive thrusting ensues.
"The first time I saw it on stage I was like, 'Oh, this is not going to work,'" he says. "She said, 'No, it's going to work, it's going to work, it's going to work. 'Then in front of an audience it kills. That whole sequence kills. It kills enough that we can actually land a huge musical number around it to get to an end of a song. If we hadn't trusted that moment I don't know how that song would have ended." Now that's collaboration.
