Quote from Cliff in Heeeeere's... Cliffy!
Johnny Carson: Doc is so old...
Cliff: Oh, my God, here it comes.
All: How old is he?
Johnny Carson: ...when he was a kid he never blew out candles on a birthday cake. They didn't have fire yet. [audience groans] Ooh, stay where you are. Fortunately, folks, in a situation like this, the, uh, the band has instructions to come over and form a human barrier in front of a star. How did that line get on the cue cards anyway? I should have done that joke with one of those big blue dots covering my face. Who wrote that joke anyway?
Cliff: I- I wrote that joke and it was great.
Johnny Carson: Pardon me?
Cliff: The problem wasn't the joke, the problem was you. You botched it. You botched my joke, Johnny Carson!
Norm: Sit down, please.
Cliff: I'm not going to sit down! I wrote that joke. Get your hands off me. Is this the way you treat your talent, Carson?! [gets dragged away by security]
Johnny Carson: Ladies and gentlemen, the president of NBC. [applause]
