Quote from Cliff in Heeeeere's... Cliffy!
Cliff: Hey! I did it! Ha-ha! I did it! l, uh, I sold a joke to Johnny Carson! [laughs] Oh, this is the happiest moment of my life! Well, take your last look at Clifford Clavin, letter carrier. Yeah, when my joke hits the airwaves, I'm gonna start a new career. Yep, it's going to be Cliff Clavin, joke meister. Doctor of Ha-Ha, the funny man. Yeah, I'm going to be hanging around with a whole new group of friends: Oscar and Emmy. Ciao.
