Croquet, Ladder Ball, Wiffle Ball, etc.
As much as we enjoy sports, we don’t want to play sports in our bedroom. Well, there’s only one form of exercise that we could tolerate on our beds. You know what we’re talking about, don’t you? That’s right; extreme sleeping. Whoever sleeps the longest is the winner!
But to really screw with your roommate’s head, do what this person did. They got a bunch of astroturf and placed it all over their roommate’s floors. They also placed a croquet set in the bedroom for good measure. You can be as creative as you like and get any other kind of backyard sporting equipment for your prank.
