It's a cheap rug. Bodybuilders, with the exception of Arnold, don't have two nickles to rub together. Now, I know that Bob Chick has a couple of sleazy deals around town and a "guy roll" (a stack of fives wrapped in a twenty) in his pocket and he's "guy rich" right now (and that will change for the worse with time, as it always does with these types). Despite the couple of bucks he's got these days, he has zero taste, as is evidenced by his wardrobe, so a cheap rug (bad toupee) would be the logical choice for the dumb mutt.
