Apparently, some men have a problem with their privates moving around in their underwear and getting out of position. The problem was widespread enough that a Japanese clothing company invented a type of underwear that prevents any sort of movement, and they even produced a hilarious commercial to prove it. 

One of the things that TOOT, a not-so-well-known Japanese clothing company, prides themselves in is their collection of sexy (their words, not mine) men's underwear. And it's not only the look of the underwear they're touting. It's the fact that a man's junk will never, ever, fall out of place. Now, for what reason this is so important is beyond me, and I should know. But it obviously bothers some people; otherwise TOOT never would have gone through such trouble to market their special underwear.

As the commercial shows, TOOT's Best Position Underwear has been tested vigorously, and scientists have confirmed the results. No matter what happens, as long as you're wearing TOOT undies, your junk will always be right where you want it to be. 

Because nothing is more important than that!
