I've never been much of a South Park fan, but I've been watching a few episodes lately, and it's just a strange combination of stupid toilet humor that's worthy of a junior high student, and stuff that absolutely cracks me up.
I can't decide which is my favorite line from this episode:
[Upon leaving The Passion] It guilts you into believing!
Cartman: If Mel Gibson was here right now, I'd be on the floor licking his balls."
Who among us wouldn't, Cartman?
