Quote from Dorothy in An Illegitimate Concern
Blanche: Oh, for goodness' sakes. Why, you two could be celebrity look-alikes. Dorothy: Oh, Blanche, honey, you really think so? Blanche: Well, absolutely. So, which one's Cheech and which one's Chong? Sophia: I'm Sonny Bono, you idiot. Dorothy: Gee, I wonder how many maitre Dd's have heard that line.
