I'm just sharing this for a moment, it's from an on-line comic called Sinfest, by Tatsuya Ishida. It's hilarious stuff. Satan, poetry, girls with attitude, God with hand puppets, and selling your soul for riches and bitches (and man-hos, can't forget the man-hos).
It's a lot like Calvin & Hobbes; well thought out, very smart, and funny as hell. It's an intelligent comic with edge. I've been reading it every day for years now. It's PG-13 I'd say, but give it a chance.
