Well, he is douche bag! :)
I really don’t think Guy is a “douchebag”... He looks pretty ridiculous, and he’s pretty extroverted, but seems to treat people well in his ‘Diners’ show. Then again, I didn’t watch the TNFS season that he won, and that show could make me hate just about anyone (Bob Tuschman and Susie Fogelson, particularly).
