I just watched episode 13 (current/ongoing season 11) of South Park titled Guitar Queer-o. It totaly blew me away, man. It was about Guitar Hero -videogame! Get it and watch it. Hilarious stuff. At least I did laugh my ass off by watching it. It seems that best episodes of South Park are the ones where they are concentrating in video games and things related. One of the most funniest South Park episodes was about World of Warcraft and there was at least two episodes about Nintendo Wii. FUNNY AS HELL!!!
Here are the links for the YouTube-clips of South Park Guitar Hero -episode and WoW-episode. I also made an avatar for myself at South Park Studios -homepage.
