I'd never seen this prank before, but maybe you have. Regardless, it's awesome. Now I don't want to spoil it, but I love how the girl put a hidden camera in the bathroom TO FILM HER DAD USING THE JOHN. Because that's a healthy father/daughter relationship.
Thanks to Towhee, who once got tape-measured off the john and hit her head on the bathtub and almost drowned. Pranks are dangerous, kids.
