I think Goodrum can't accept the challenge because the poor negro don't have $500 to bet with. His excuses makes no sense. Since he is dieting anyway, why not take the bet and make some money in the process? So what is Disturbia can't get into shape, that's easy money for Vince. Something doesn't add up. Either this piece of shit don't have the money or he is woefully out of shape and can't compete. Which one is it?
