Not a personal prank to myself, but I just went out for a meal in New Malden with the family and we had a window table, so we could see a guy walking up and down outside wearing a purple feather boa and Rudolph antlers, carrying a camera tripod, which he set up in the middle of the High Street, so we thought he was going to take a picture of the rather hopelessly designed Fountain at the end of the road. Instead, he jumped about three feet onto the block of a lamppost and dropped his kecks and stood there naked until the camera took his pic, an image which has stayed with me. Whether he is an art and photography student or whether he just felt like doing it, I have no clue!
