Porta-potty pranks are a dime a dozen, and you may think you’ve seen or heard of them all. But the one shown in this video is quite original, and it leaves its victims thoroughly confused.

I’m not sure where they came up with the idea for this prank. Maybe one of the pranksters had a bad dream that was similar to it. But imagine going into a porta-potty, doing your business, and opening the door to find yourself in the middle of a serious business meeting. How embarrassing would that be?

It’s a good thing the unsuspecting victims have already been to the potty, because something like that might otherwise make someone piss their pants.
