Last night's episode of South Park was a take on Salvia, that legal drug that kids can take that make them freak out and fall over, only to wake up and find that their friends had immortalized their trip on YouTube. In the episode, the kids learn they can get high from inhaling cat urine, so Kenny tries it out. He quickly becomes addicted when he discovers that tripping on cat urine brings him into the universe of the 1981 movie Heavy Metal, where everything is pretty much boobs. The song from the movie, "Heavy Metal (Takin' a Ride)" might be our favorite new track. Clip above.
