The next time you hit the beach this summer, don't be surprised if the water is looking more yellow than a school bus.

A new study has found that 62% of people admit to urinating in the water at the beach. A total of 48% said they've done it more than once, giving some credence to that whole "nature's toilet" nickname.

There may actually be a reason folks are making their bladders gladder in the water. About 54% say beach bathrooms are the worst around, topping ones that can be found in airplanes (23%), the gym (11%) and movie theaters (11%). Still, you wouldn't walk over to the beverage cart, treadmills and concession stand and do your business there, would you? Would you?

Moral of the story: if you want to go for a swim this summer, find a pool.
