Student prankster Dan Jarvis rushed the pitch - er, pool - at the World Diving Series in London's Olympic Aquatic Centre on Sunday and ripped off his clothes to reveal skimpy Speedos before taking the plunge from a 10 metre board.
With a security guard in hot pursuit, 26-year-old Jarvis bolted up the stairs flinging his clothes to the wet floor below. Sadly for him, he dropped his house keys in the pool before jumping off the platform, causing the event to be held up even further. He received a £90 fine under the Public Order Act.
"It was just a bit of fun. The guy who was getting ready to dive on the top board was laughing at me," Jarvis told The Telegraph.
