Quote from Martin in Frasier's Imaginary Friend
Daphne: I think you two are just being awful, I've never known Dr. Crane to tell a lie. Niles: Actually, this is not without precedent. When he was ten, he forged letters from Leonard Bernstein and told everyone they were pen pals. Martin: Oh, yeah. Niles: He'd come bounding up the stairs, "Got another one from Lenny"! We were all agog until Mr. Bernstein wrote that his Broadway debut was "Candide" when everyone knows that it was "On The Town." That's when we knew it was a fake! Martin: The sloppy kid lettering was also a clue.
