I understand there's a Monkey's Elbow, Kentucky.

There's also a Red Dick, Kentucky.

I live in Loveland, Ohio. That's somewhat eccentric. There's also Loveland, Colorado. (Loveland, OH was first.)

I always found Truth and Consequences, New Mexico(I think) interesting.

Then there's the town in Oregon (or one of those other square-shaped western states) that changed its name to Half.com.
