brushing-excretion combo?

So I was wondering if it is cool to brush your teeth and pee at the same time. I wonder because I was brushing my teeth last night and then realized that I had to do the #1....so I did. And there I was, bushing my teeth and draining the plumbing all at once. And I thought, "Dude, what's wrong with you? Well, actually, is it so bad? Kinda. But I don't care. Or do I?"

So I carried it to the next level and thought, "Is it cool to drop the kids off at the pool and brush your teeth at the same time?"

Well, is it?
