What is the best prank u can think of?

Just can't beat ghost pranks

Put clear ceramic inpakken, wrap around the toilet zitplaats, stoel 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 vrienden head and yelling "spider!" XD it's so easy to do and almost everybody falls for it.
