Scare the shit out them!!!!
More about Scare the shit out them!!!!
Hide in the shower, and when someone comes in and begins using the bathroom, pop out with a fierce and frightening scream. Whoever this prank is pulled on is likely to start running before their brain can process what is going on and tell them to first “stop” going to the bathroom. This is a pretty sick, mean prank, but hey, boring pranks are for boring websites, and we aren’t one of them.
