There’s a British panel show I’m addicted to (QI), and one of the frequent guests in its earlier seasons was American comedian Rich Hall. I always thought that he looked strikingly similar to Moe Szyslak but just chalked it up to coincidence.
After years of wondering, I finally bothered to look up who Moe was actually based on. Lo and behold, it’s Rich Hall.
So, I guess it’s less “today I learned” and more “today I confirmed my random theory”.
What’s funny, is that’s the kind of joke Hall would make.
I’m not sure how much of Hall’s personality was factored into the character (there’s another source for some of Moe’s characteristics), but that line is definitely in Hall’s style.
