IPhone droped in the toilet?

Is it only teenage girls who do this, is it because they keep the iPhones in their back pocket? It seems like it is almost always iPhones that go for a bathroom swim.

A lot of people do it. They're not heavy so easy to slip out of hands/pockets

The back pocket explanation is always what I've assumed, but I'm completely convinced that iPhones must be attracted to water. Based on the sample we have access to here, it must happen hundreds of time a day.
