It's a practice most people grow out of as a child, but it seems for Olympic swimmers when you've got to go, you've got to go.
United States Olympians Ryan Lochte and Michael Phelps have both admitted in post-Games interviews that peeing in the pool is common practice among swimming's elite.
Lochte made the admission in a radio interview with Ryan Seacrest, going so far as to say it was "automatic" when he got in the water.
"Of course. We always do," he said when asked if he had ever relieved himself in the pool.
"I think there's just something about getting into chlorine water that you just automatically go."
Phelps was also forthcoming with the admission, telling the Wall Street Journal it was "a normal thing to do" and the "chlorine kills it so it's not bad".
Lochte and Phelps were both gold medallists in London, with Phelps finishing the event with six medals to become the most decorated Olympian of all time with 22 medals.
