When I was in middle school, some kids in a car were throwing eggs at a friend and me, so we went in the house and got some eggs of our own. When they came back around, we let them fly. Unfortunately, my friend walked right into my line of fire and I hit him in the back of the head with my egg. Probably saved us an ass-whooping, since the guys in the car were laughing instead of angry.
Time for egg control! ;-)
