If anyone's interested, there's book called 'Rude Britain' that runs down a list of the top 100 rudest place names in Britain. I find it absolutely hilarious (I have the kind of sense of humour) that there are places called things like Swallow Breast. And Fingringhoe. And Titlington. And other much ruder things.
There are some truly magnificently weird village and town names dotted around Britain though, I guess from the constant mixing of languages. Two of the best - we went on holiday to Devon last year, and on the drive down we went past Queen Camel and Bishop's Nympton. I don't know what a nympton is, but it sounds painful.
ETA I can't believe nobody's mentioned Ugley yet - a very charming village not too far from where I grew up that never failed to elicit giggles on driving through.
