Head Hunting

If you're tooling around Manhattan and nature's call strikes, you can go to Diaroogle.com, "the premier toilet search engine." Provided, of course, that you carry one of those smart phones that all the kids are talking about these days. The site reviews and ranks more than 200 potty places around town on a scale of 1-5. The site mentions that in an absolute emergency you can always ask politely at any firehouse.
