What Is The Best Prank Ever?!
Question:
What Is The Best Prank Ever?
Answers:
Saran wrap pulled tightly over the toilet bowl, under the seat... works best for a guy's bathroom when he tries to urinate. Just don't do it in your own bathroom.
Also: urine in a Frisbee -- frozen to maintain disk-shape... slide it under the door of someone else. Let it melt.
