Comedian/actor Billy Crystal spends over $4000 a year on prepaid cellular phones that he uses to make prank phone calls. He claims that it keeps his "comic chops" fresh. He even tried to claim it as a business expense on his tax return until his accountant talked him out of it.

When Hollywood producer Jerry Bruckheimer throws a dinner party at his house he puts out a chair that is completely made of papier-mache. In looks it is indistinguishable from the other chairs but, of course, when someone tries to sit on it it collapses. He thinks that this is a great joke. When the chair collapses, he flips a coin and either gives the victim $1000, or kicks them out of his house for allegedly breaking an antique chair.

Actor George Clooney is a well-known prankster on movie sets. But one time his pranks backfired on him. He baked a number of cookies using rabbit droppings instead of chocolate chips. He brought them to the set of Ocean's Eleven and called them "vegan chocolate chip cookies". Actress Julia Roberts was warned about the cookies. She pretended to eat one and get sick and then hired a doctor to convince Clooney that she was suffering from tularemia or "rabbit fever". Clooney was so upset that he donated over $50,000 to the hospital she was being treated in before she let him in on the joke.
