also around halloween i put the adult end of a baby monitor in my roommates air duct. waited till the middle of the night. then started makin scary ass noises into it and beating on his window.
scared the fuck out of him!
My friends and I once melted down chocolate laxatives and added them to a brownie batter. We then baked brownies and brought them to a party. I guess all of the laxatives were concentrated in one area of the batter and no one got any affect except this one girl who was in the bathroom for the whole party. People had to start shitting in their neighbors bathrooms.
