Okay, 1) We get a bag of poop and some underwater napalm. 2) We evolve and grow legs. 3) We buy the guy a house with a door and a doorbell so we can ring it.
4) You disguise yourself as Bigfoot and make sure he sees you through the window out the back of his house.
Then we put it all together into the prank of the century.
How's he going to stomp out the bag if we evolve and grow legs but he don't?
