Fill my college roommates place with two feet of water as a prank
I am gonna caulk and duct tape to waterproof everything, doors, stove, fridge, drawers. He's coming back from vacation tonight and I told him to go thru the window cause the door is stuck (it's nailed it shut). He is gonna jump in then I shut the window behind us and lock it. It'll be pitch black cause that's the only window then I beat the crap out of him. Is this a good prank?
