Is that worth knowing? Maybe not, but I think it's interesting.
Where I live, in the U.S., horses don't have names on them, except at Disneyland, pretty much. The "King Arthur Carrousel" in Disneyland was made in Canada, over 100 years ago—before Disneyland. I don't know whether the Canadian builders used two "r"s in the name, or if Walt Disney liked the alternative spelling. If you think any of this is interesting, you can read more here, about the one at Disneyland.
I took the photo above, at a fair in England. Lol is a nickname for Laurence, there (and old guys are named Laurence, not so many young kids), so that horse was named after someone who was called "Lol" instead of "Larry," and not named after laughing out loud.
How many small facts and connections can one person hold? I don't think there's a limit.
It's easier to learn a thing if you already know something else kind of like it. Connections!
