I was walking to the bathroom this morning in my dorm, and there is a tire next to the door. The note taped to it read: [Dorm mate's name], Is this yours? Happy April Fool's! P.S. Where are the other 3?

Luckily, she hadn't woken up yet, and i made sure to be out of there before she did, she has a rather loud temper. My friends who live downstairs wouldn't tell me who did it, just that it wasn't someone who lived in our dorm. I think its rather ingenious and hilarious! :)
