Which one of the characters not featured as part of the main cast are your favorites and why?

For me, it has to be Chuch Coleman, he has such an eccentric behavior that makes you want to crack up just looking at him. He is also a great friend to Kevin and brings more comedy.

Also, I'd have to say Coach Cutlip comes in a close second, because of his seriousness, yet he was also sensitive (remember Santa?) to his kids.

Kirk Mcray, &Randy Mitchell reasons I have no idea.
