Around where my sister lives, there's a Street Road. This has always made me smile for some reason.
I've seen the "road wet during rain" sign - there used to be one on the way to the grounds we camp at. Unfortunately, I think they finally realized how ridiculous that is because it's not there anymore...
A while back, my mom and I took a road trip. On our way back, we got completely lost - and ended up driving through Circleville. Circleville has a Mooberry Street and Friendship Lane and signs pointing out how to get to Stringtown. Maybe it was because we were a little cranky due to being lost and both of us were only awake due to drinking sugar with tea in it, but we both completely lost it. We swore it was like something out of a preschool cartoon...
I've also seen "Shoplifters will be shot. Survivors will be prosecuted." in a shop.
I thought of a lot while reading the thread but now they've left me...
