I’m not going to make a career out of baiting some fucking religious fanatics, you know, by insulting their prophet. I wouldn’t do that. That seems crazy. But then, after they got killed, I just had to draw that cartoon, you know, showing the Prophet. The cartoon I drew shows me, myself, holding up a cartoon that I’ve just drawn. A crude drawing of an ass that’s labeled “The Hairy Ass of Muhammed.” [Laughs.]
You did what?!
Yeah, I sent that to Liberation, so we’ll see what happens. You know, that’s the most I’ve stuck my neck out for a long time…

Late addition before publishing:
Apparently, the cartoon has been released:
