My favorite is xkcd (http://www.xkcd.com). The disclaimer really says it all... "Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors)."

Yeah, I'm a dork.

You see these shackles
Baby I’m your slave
I’ll let you whip me if I misbehave

Tie me to the bedpost

I like it rough
cause I'd rather feel pain than nothing at all
