When your kids are asleep you start preparing this epic april fools day prank. Turn frames, paintings, photo's and all other stuff upside down.

This prank needs some preperation but is really worth it. Your coworker will show up and his keyboard will be full of little grasplants!

Hang up teabags outside someones room. It's excellent to do this to your roommates for an extended period of time, eventually they will lose it! You'll see :)
