Though a Toilet Monster sounds like a plunging problem, this one sounds like a lot of fun, and could definitely be good for a few laughs. Just attach this monster to the inside of your toilet bowl with the included suction cups, and wait for your victim’s time to go. The next time someone lifts the lid, they’ll be in for quite a surprise. A few of these pranks, and you’ll never get told to put the seat down again.
