Mario Lopez is on of the very best commentator I've seen. Not joking either.
He knows his shyte.
He's also had "the pleasure" of sparring with Manny Pacquiao. His words.

He's the most successful of the Bell Kids. Next is Zack with NYPD Blue and westerns I believe.
Then it goes downhill from there. I actually know how badly the rest are doing, but I don't
even want to talk about it.
