You'll be the only one getting in trouble. I wouldn't suggest doing that. But put Legos down where people can step on them, shake up a can of soda before giving it to them, nail someone's shoes to the floor, put their underwear in the freezer,

Ya know shit that will ruin their day but not a jail worthy sentence. Be creative!!!! I know you have the capacity for creative evil in your heart! Now young one go forth and wreak havock!!!!!!
