According to sports writer Ian Stafford, the British hold the record for winning the world's oddest competitions . In one of these bizarre events, contestants contort their faces and are judged on their ugliness. One competitor removed half his dentures and reversed the other half, rolled his eyes, and tucked his nose into his mustache and upper lip to achieve prize-winning ugliness. Another of these eccentric contests is snail racing. Opponents in this case are, of course, snails, which are placed in the center of a thirteen-inch cloth circle. The first to reach the edge of the circle wins. The race often takes four to five minutes, although the all-time champion (owned and trained by an English seven-year-old) finished the course in two minutes. Toe wrestling, bog snorkeling, worm charming ⎯ the British have emerged as unconquered rivals in all of these so-called sports. Perhaps you think that sports writer Ian Stafford should win first prize in the Biggest Liar in the World Competition. No, every one of these outlandish games exists. You can check them all out on the Internet.
