I decided to pull a prank on my friend while he was taking a shower. I pumped up my bb guns several times and then aimed it at the shower wall hoping for a harmless ricochet. After I pulled the trigger I heard him scream, fall down on the shower, and then start crying. Having no idea what to do I ran out of the room. When he approached me about it later, showing me his massive welt, I said I had no idea how that could have happend!! SYIH!
