P ranks are wonderful, for the one playing it of course. It is terrible for the one who gets played maybe to the point that they actually get afraid or something. When it's revealed who played the prank, the revenge time starts. But, pranks can go wrong, not just wrong even horribly wrong, like really. It depends on the person you're playing the prank on and well what people understand and, of course, many other factors also come into play. Good luck before you play prank with such people.
