Gross.. In principle it seems kind of cool, but unless those ducks are in diapers, count me out..
And you really think humans pay attention to the "don't pee in our pool" signs? The ducks are at least doing duck things - ducks relieve themselves in water. Humans have their bathrooms right there outside the pool but I'm sure there are tons of kids and adults who don't bother to get out of the pool.
