"There's something about getting into chlorine water that you just automatically go," he said.
"Like animals, they mark their territory. I pee in the pool, that's my territory," Lochte says.
"I have a book that's coming out, 'Fifty Shades of Yellow,' it's supposed to be a bestseller," he adds.
Though Michael Phelps and British swim star Rebecca Adlington recently came to Lochte's defense, claiming that, "everybody pees in the pool," British Prime Minister David Cameron does not approve.
"I was quite surprised by that," Cameron said of Lochte's revelation in a recent interview with UK's Metro.
"It is not OK to pee in the pool," he added.
Lochte also appears in another Funny or Die video called "The Olympic Ticket Scalper." It also stars Patrick Stewart, Simon Pegg and Maisie Williams.
