Prank my housemates

My roommate always ate a shit ton of cereal/Mac and cheese that he kept on the top shelf so one day I bought a carton of eggs and fishing line. I tied a string of line to every box, then taped an egg to it. For a solid month, every time he wanted cereal or Mac, an egg would fall and splat in front of him on the counter and I would just die laughing in the other room. It was really funny when he thought he got all the eggs but went into another cupboard to grab a box of pasta and another egg came crashing down. All I heard was "fucking dammit tony!! Fuck your eggs!!"

This pretty much started a prank war, every time including eggs.

not sure if you can find a good door to do this with but cups of water are full lol

This thread. Is golden.

Or he could get a hamster cage and put a small hole in it. He could then put a note taped to it saying, I got you guys these hamsters as a parting gift and I think the female one is pregnant so you guys will have baby hamsters! The room mates will think that the hamsters have escaped and search all over for them. Whenever there was a mouse in the apartment they will think it is a hamster.

coat their rooms with duck tape some on every surface

ahahaa! thats a good one. did the eggs rot?
