Fingringhoe and Penistone have got to be up there.

Ballywatticock is a contender. Shitterton is funny because it literally means what you think it means as it was next to an open sewer. When I was younger I thought Ballybogey was hilarious.

Technically you could count "Derry/Londonderry" as a de facto placename as a whole by how it's used, even though it is technically two names of the same place side by side. But I realised how bizarre it is for people who don't know about the history of it, and come into a bus or a train station and hear an announcement for "Derry-London-Derry" or see "Londonderry Derry" on Google Maps.

Another one I like is Torpenhow Hill. Basically Tor means hill. Then someone invaded and the name changed, saw a hill at Tor and called it Tor Pen, which also means hill. Then another group comes along and adds their word for Hill as "How", and then finally we see the hill and add the word "Hill"

Lisburn is another contender. While most places with "burn" in the name refers to a river, Lisburn is named that way because it's the rebuilt part of Lisnagarvey that burned down. There's even a phoenix in the armorial achievement.

There's obviously all the quality rude ones like Bell End/Wetwang/Shitterton/Penistone etc, but for a question on Lemmy, I'm pretty sure Barton-in-the-Beans (Wiki link) would be most appropriate.

Not crazy, but I always thought Giggleswick and Wiggleswoth on opposite sides of A65 is funny.

I grew up near Slut's Hole Lane. It didn't have a sign at the time and I only found the name on an old map, but the sign has been put back since.

More recently a regular walk would take me past a woodland called Fiscal Policy. I did find an explanation for this one. I can't recall the details, but it was rather dull overall.

Came across this when I visited Shetland. Which might be one of the most beautiful places in the world.

Edit: We also visited Twatt. But for the life of me I can’t find the picture.
