When I was a kid, I went to baseball camp. One night another kid in our cabin had Oreos. He gave us all a handful of Oreos just before lights out. While we were eating them in the dark in our bunk, someone screamed out "Ow!" The counselor said stop making noise and the kid said "I can't help it, I just got hit in the head with an Oreo". Soon other kids were screaming and a full food fight broke out in the dark. When we woke up the next morning, there were black marks on all the walls. Of course it became a nightly tradition.
