To be honest, I don't care what kind of personality he has. He put a very good fight over one of the top favourites on the show. I bet that if Charles did more then just cover up during his fight with Sell he would have had a better chance. He had a few sick subs executed throughout the fight and Sell wasn't as dominate as the Spike producers cracked him up to be.
On the note of his personality and all, I think he is pretty damn funny. He is highly entertaining and I will agree with others, the treadmill fall had me cracking up.
