Blazing Saddles is funny. You know it, I know it. I've laughed at almost all of its jokes. Almost all. I never got the joke where Mongo's ox has "yes" and "no" written on its buttcheeks.
If someone knows, explainify it! I'll accept perhaps never laughing at the joke anyway, because it's been maybe 20 years since I first saw the flick and I still haven't laughed at that part. Boggled, yes, but not laughed.
