You sat next to Matt for real? Sweet!
I was a senior and he was a grade or two below me, so of course I pretty much ignored him and and vice versa. We weren't unfriendly, but I didn't hang out with him or see him outside of that class.
My littler sister, on the other hand, knew him pretty well. She went to live in LA and apparently ran into him at a party - AFTER the movie came out. She, also being a libtard only interested in her own life, asked him what he had been doing. He said, "Oh doing a little cartoon for Comedy Central called South Park. My sister was clueless, and had no idea what a success he had become.
