I just saw one of the most "out there" scenes in all of South Park. Cartman goes to testify in front of the Congress to petition for stem cell research (he's in posession of a bunch of aborted fetuses that he can't sell because Congress outlawed stem cell research). He talks about his dying friend Kenny, then he starts to sing Asia's "Heat of the Moment"- a cheesey 80's pop hit. In the middle of he song the congressmen join in and it turns out everyone knows the lyrics. This is so surreal its holarious.
Who wants to share their favorite/memorable South Park moment?
