That movie rocked. A fine example of Parker/Stone humour.
Speaking of, do they still show 'Thats My Bush' stateside? That show is feckin brilliant as well! It comes on here at 3am, so most people have to tape it.

I'm looking forward to the second season, which has been held up due to the legal battle around it, that shows the daughters as incestuous lesbians who drink and party all the time.
