My sister was stationed in England at the same time I was doing my stint in Germany, and when I visited her there we enjoyed noting the strange place names. One nearby her Lakenheath station was Six Mile Bottom, which we thought was worth naming a place for. That's a big bottom!
The New York Times reports today on other place names there that seem to have escaped us, such at Titty Ho, Penistone, and Spanker Lane. "No Snickering, That Road Sign Means Something Else" points out that although you may have claimed your home town (or the one you live in now) is the armpit of the world, at least no one could claim that you must have grown up in Butt Hole Road.
