The concept of honesty finding comedy in being blind seems to go over the heads of a lot of sighted people in my experience. It’s easy to startle a laugh out of them with a few quips that amount to dad jokes but when a blind person says it, it’s always funny in a sort of gallows way. And I think threatening to turn the lights off on a sighted stranger next time they go down a set of stairs would be confusing to them; you kinda need to know someone who’s blind and sarcastic for a bit before that registers as a joke or even something that makes sense.

As for sighted jokes I don’t get, anything involving a subtle gesture as the punchline will do. Or a description of something most people can see but I have no context for. Even when it’s explained I usually don’t get it. There was an image pun about Bluetooth I couldn’t parse because I didn’t know Bluetooth has a symbol.

I suppose like in all fields there are jokes that outsiders won't get, scientists, programmers, doctors etc all have their pools of jargon and the blind are no different.

As a blind person who's never had sight, I'm also sure there are visual things I just can't appreciate.

Yes, there is a very funny joke only blind people understand.
