I live in a town that is affectionately referred to as (pardon my language) the Elephants Arse hole, or the Arse hole of Ontario. We didn't know this when we moved here and it came as a shock the first time someone said, "Oh, you live in the elephants arse". I was quite put out I must say especially as Owen Sound is actually one of the nicest old towns in Ontario.
This is how we earned our name. [link]
