Sunday I'm leaving for a week long soccer camp. There are usually 100 kids and we stay in dorms at a university. The girls rooms are upstairs and the boys are down stairs. BOYS CANNOT GO ON GIRLS FLOOR, GIRLS CAN'T GO ON BOYS. The kids range from 10 to 18 years old. We eat three times a day practice three times a day and go in the pool once a day. Anyways, we work really hard at the sessions so me and my team mates always like to spice things up and make it fun! we want to prank our coach or maybe the younger girls at the camp. Nothing that will hurt them, or ruin the dorms. just some harmless innocent but funny pranks. NO FIRE DIRLLS. any ideas?
