At what point does one realize they have a talent for synchronized swimming? Does it originate from one's ability to hold their legs together during an underwater hand-stand? The ability to splash silently during Marco Polo? Or how affectively they can execute Nomi Malone-style sex-flailing for style points?

From Radar's article on the Beijing-bound U.S. synchronized swim team, it's much more strenuous than that.

"It's like sprinting and holding your breath at the same time," says Christina Jones, a seven-year veteran of the national team. "People who mock it have never tried it."

So, curb your mocking: these are highly-trained athletes.
