I am wondering, because I always seem to find a lot of things funny that others don't. Many things that make me laugh don't even seem to affect others, unless they are commenting on how weird it is.
Most of the stuff I seem to find funny is ridiculous, silly or insane, and that's why it is funny to me. It is just so preposterous that I can't help laughing. Maybe it is because I am so logical that when my mind can't process the craziness of it, it becomes funny to me. I watch a lot of crazy nonsensical YouTube videos which I find hilarious, but if I show them to others they either say, "That wasn't that funny," or, "You're so weird." Now I usually keep my ridiculous videos to myself.
I also like wordplay and puns. But I always seem to be the one person who takes like 3 full seconds to process a pun or similar joke, and then I only start laughing after everyone has already made the connection, reacted, and moved on to something else. There was one time that a teacher made a joke like this, and then soon after handed out a quiz. The whole time during the quiz, everyone was silent, and I kept remembering the joke. I was trying so hard not to laugh, but for some reason that I couldn't understand it was really hilarious and I would start laughing again. It was so flipping awkward, especially because I'm pretty sure they knew why I was laughing and it wasn't even very funny to them.
I do find some of the more popular type of jokes funny too, but only certain ones. I don't really like movies like "The Hangover", which a lot of NTs seem to find hilarious. I guess I can find some parts to be funny, but not really. I think what I don't like about a lot of NT humor is that it tries to make something that is stupid or over exaggerated seem believable. If it was clearly ridiculous and meant to be that way, I think I'd find it more funny, but when they try to apply it to real situations is when it annoys me.
Edit: Now that I think about it, I guess I don't find all puns and wordplay to be funny, but I don't really know what decides whether I think it is funny or not.
