Replying to flying dog shit in my face

so my brother and i always have to walk the dogs, and we have to pick up our dog's shit in plastic bags, yeh yeh you know that shit. well anyways, to make the walks a little interesting we pick up our dog's shit and whoever gets to the shit first, gets to throw it at the other person..and the game proceeds into a dead sprint away from one another. and knowing me i should know about bad karma, but tonite my brother got to the shit first, picked it up and hucked it at me...only to find out that the bag had a hole in it and exploded in my face. yeh, exactly, what would be your reaction be to having 2 lbs of shit on your face? i got home and i almost threw up, the stench reaked so fucken bad..help me think of some ways to beat his ass
