What is the best prank আপনি can think of?

Just can't beat ghost pranks

Put clear ceramic মোড়ানো around the toilet আসন 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 বন্ধু head and yelling "spider!" XD it's so easy to do and almost everybody falls for it.
