Well most of my time looking through the atlas in Geography lessons was looking for places with silly names, but I think I'd be competant enough to read a map if I needed to.
One place I saw in one that I'll never forget just because the name sounds great, a place in Scotland called 'Sloy' I intend to go there someday just to take a photo of me in front of the sign to show to one of my friends

Ooh and a place not far from here is called Badgers-bank
What is the funniest place-name you've heard of?
