Just look for the baddest F-body in Mafia and throw down on him. If you kick his ass, you get to claim victory over all of them by default. Easy! If, OTOH, you get your ass thumped, well that means you have to eat a little crow and suffer through all the jabs that the nutswinger F-bods will be throwing at you. But, hey, that's the price you pay if you're gonna go brand bashing.
