I am one of the few people on earth to have witnessed, and participated in, a great prank. 30 years ago, a friend of mine was diving in the Columbia river, and found a submerged rock partly stuck in the riverbed. He pulled it out and thought that it resembled a meteor, the kind we saw as students. He was not an idiot and did not think he actually had a meteor. But he knew who might. He scorched on side of the rock, then took it to her backyard at night, pounded it into the ground, and scorched some of the grass. A few days later, he gets an excited call from her about the meteor in the backyard. She then took it to a local university scientist (astronomy, geology?) to ask his opinion. He wasn't strongly sure, but said that it might be. He advised her not to tell the media, as she was renting the house, and the landlord apparently would own. So, she wrapped the meteor in a blanket and put it on the shelf in the closet. So, now she thinks she still has a meteor.
