Luke was a bad guy, he did drugs, he smoked up, he drank, he stole, he was a bad guy.  But yet he was still cool in his own way.  He was first really seen when he congratulated Kathleen for havinga good performance at the battle of the best.  He was then seen when he gave Shane some acid, that's when Shane jumped off of the bridge.  I liked it, it was cool.   He got to high school and was still a bad seed...he can be seen in the retard class with Joey and Duane.  He hung out with Yick and got Yick into Marijuana, that's no good.  He made fun of Arthur and played Poker with Joey and Yick.  Arthur came and whooped him so then they sort of became friends. That's about all for Luke.
