What is the best prank Ты can think of?

Just can't beat ghost pranks

Put clear ceramic заворачивать, обертывание around the toilet сиденье, место, сиденья and when someone goes to the bathroom (especially boys/men) their urine will spray everywhere. XD

nothings funnier than putting a piece of lint on your Друзья head and yelling "spider!" XD it's so easy to do and almost everybody falls for it.
