I really don't think that is a toupee. I think we are just used to him with his bad perm and now that his hair is straight it looks just as bad. The worst toupee on tv is worn by ESPN's Karl Ravich. Who is he kidding?
A friend of mine had an interesting take on Fratello: http://sportsillustrated.cnn.com/2005/writers/kelly_dwyer/02/07/listless2/index.html I've seen Keady and his wife at a grocery store before, and strange as it seems, his wife is ten times scarier than he is. She looks like the old lady from "There's Something About Mary."
