Lol our school went to camp and at night the cabins had hardcore pillow wars because the teachers didn't give a stuff as long as you didn't wake them up, I ended up getting thumped by the biggest kid in school and flew and hit the bed, painful but fun. The teachers never found out, just our high-school counselors that were "watching" us. I could say more but this was 3 years ago and a vague memory.
