Yeah it works basically the same as Garlic with a vampire, but it doesn't keep you safe from suicide bombers. For suicide bombers you have to carry around a porn (preferably hardcore anal creampies), that really gets em good.
Maybe we should start putting porn everywhere, in busses, on trains, in planes, all with blonde big titted women, that'll keep these assholes from exploding in public.
Or wait, i'm getting another thought...
