On Location: George Carlin at Phoenix1978

George Carlin:
[about taking "motherf***er" off the list of seven dirty words] And by now, cocksucker is the dominant word on the list. Previously with motherf***er on the list, cocksucker was somewhat balanced out. They were the only multisyllabic words on the list, but now cocksucker stands alone. Sh*t, piss, f***, c*nt, cocksucker, tits. And who knows? Maybe it doesn't belong, either. After all, motherf***er turned out to be a ringer. Let's take a look at cocksucker.

[laughter]

George Carlin:
See if this one belongs; we'll divide the word cock and sucker from each other, those words. Sucker isn't dirty; sucker, that's... it's suggestive as hell, but it isn't dirty. And cock... that's not dirty all the time. That's one of those words that's only partly filthy. Cock, if you're talking about the animal, it's perfectly all right. They used to read that to us from the Bible in third grade. And we would laugh, man.

[laughter]

George Carlin:
"'Cock' is in the Bible!" Remember the first time you heard about a cockfight?
