This is my favorite scene from "Waiting For Guffman". The lines that Catherine O Hara says are so weird and funny.
"You know I want to try that less-is-more kind of acting where you just ... when you're talking to someone, you close your eyes, and then you look at them, when you're not talking to the person, I mean you open your eyes when you're looking away, but then when you talk to the person you go like that and you open your eyes and you look back at the person, but you never open your eyes when you're talking to them."
