What a classic George Carlin video!
The 7 words are (with examples):
1. Shit – The bird shit on the statue.
2. Piss – I have to piss like a race horse.
3. Fuck – Fuck you.
4. Cunt – She has a gorgeous cunt.
5. Cocksucker – Go to hell, you cocksucker.
6. Motherfucker – You are a motherfucker.
7. Tits – Hey, nice tits.
A little about Carlin:
Carlin was especially noted for his political and black humor and his observations on language, psychology, and religion along with many taboo subjects. Carlin and his “Seven Dirty Words” comedy routine were central to the 1978 U.S. Supreme Court case F.C.C. v. Pacifica Foundation, in which a narrow 5-4 decision by the justices affirmed the government’s right to regulate Carlin’s act on the public airwaves.
