Usually when I make a joke I am being sarcastic or ironic. Unfortunately, NTs usually think I'm being serious for some reason, regardless of the absurdity of what I am saying. Then they either think I'm a total crazy, or that I'm rude, depending on what I said. The only time people ever laugh at my jokes is if they weren't really intended to be jokes, it's usually when I just say a thought out loud that I didn't really think of as funny to begin with.
Example: Just a few days ago, there was a guy after work that was classifying everyone that works there as a type of character that would be in a sitcom. When he got to me, he paused (it seems people never really know what to think of me), and then he said, "You would be the quiet black guy who just keeps to himself." I was thinking, yes, except I'm white, very much so. Then someone else said basically the same thing.
Now I was thinking of myself as being a white black guy (I don't know what that would even really mean, an albino black person maybe?). I was also thinking that if there was a "quiet black guy who keeps to himself" in a sitcom, and doesn't actually serve much purpose in the show otherwise, that would mean he is just there for the sole purpose of being the token black guy in the show. I combined these two thoughts and said quietly, "I'm the token white black guy."
I was just saying my thought out loud to myself, with no real intent of joking or anything. But one of them heard me, and then said, "Did you just say you're the token white black guy? Only you would say that." and they all seemed to think it was extremely funny I don't think they were laughing at me, maybe it was just the absurdity of what I said.
