        Ah, but do bullets work in this case?  Shoot Happosai?  The man 
survived explosives already, being buried without sustenance, and generally 
being smacked at by lotsa things.  Heck, I don't even think you could shoot 
Shampoo and take her out; and I'm definitely not suicidal enough to risk her 
surviving the shot.  From the density their forms must have to do the kind of 
things they do, I seriously do not believe a standard, or even HP, HE, ACP, 
DU round is gonna do the trick.
        Actually, I'm surprised we haven't seen Ryoga doin' the very 
cool-lookin' wandering through the waftering heat after a big ol' nuclear 
blast.
