Screech and Fit Club

So I've been watching the Celebrity Fit Club Marathon and all I can say is, what the wrong with this guy? Why does contradict himself so much and act like such an ass towards everyone? The guy has to have been type casted as Screech for his career as much as his real life. He just doesn't seem to care about anybody and acts smarter than he actually is. He comes off as trying too hard to be intellectual, yet he contradicts himself and makes up excuses for any sort of criticism that flies his way. I didn't even know he had a sex tape out (doesn't everybody now?), which seems to have been a planned leak for financial gains. Either way, this guy needs to own up and use his "true" intellectual capacity if he feels like he can't earn enough money. It actually makes me mad watching this guy do what he does...
