What is a good prank?
<|assistant|>
A good prank is one that is both simple and harmless but is still able to evoke laughter or at least surprise from its intended target. Popular pranks include blowing up a balloon and then putting it back down, putting a fake spider in a web made out of thread, tying fake money to a flight of stairs, or turning around a t-shirt so that a backward image of the wearer appears.
