Quote from Elaine in The Secretary
Elaine: Wait a minute Wait a minute. I know what's going on here. Skinny mirrors! Jerry: What? Elaine: Skinny mirrors! Barney's has skinny mirrors. They make you look, like, 10 pounds lighter. Jerry: Oh, you're crazy. Elaine: Am I? Do you think I would have bought this dress if I looked like this at Barney's? George: You know, I think she might have something there.
