But as this article from the NY Times shows, we didn't know just how funny!
Current favourites I've seen recently include Hatch Warren, Over Wallop, Middle Wallop, Woking, Dorking and Reading (said Redding). And of course our old village Awbridge, said Aye-bridge. Not to mention Milton Keynes' Cock and Bull pubs, the origin of the phrase "a cock and bull story". In any case, I already found British place names reasonably amusing, so this article just confirms it.
I noticed on our roadtrip that the US had a lot of "Buttes" and "Butts", though. It's all about how the language has changed over time.
