This is rather getting disgusting don't you think?
People who piss in the pool have to be really lazy to get out and go to the bathroom. I mean thats really gross. But here is a funny trick you can pull off fairly well. Get a candy bar and throw it in the pool. Everyone will just scream and get out because they think somebody took a shit in the pool
You ever see the movie Caddy Shack. Just like that when someone threw a candy bar in the pool. Everybody thought it was a shit.
Its a great april fools joke.
