Peeing in the Shower...Seriously?

A friend of mine read a recent magazine article that talked about saving water by peeing in the shower. Seriously? That is gross. They said that instead of flushing the toilet just tinkle while you shower. Now I know many a friend who does this but it's just gross to me. I've never done it. I also don't pee in pools or in the ocean. Call me weird but I think there is only one place for tinkle and that's the toilet.
