...weak and instant?

Oh dear. I can't believe I just wrote that.
I'm terrible at being funny. The kind of unfunny that means people close to you put their arm around you and say "I love you, (purpletoupee), but the things you say, they don't make sense."

I'm content with having a good sense of other people's humour.
Though, tbf, I've had very little practise as I'm not a sociable person to say the least. I also literally feel like I have a gun to my head in most social environments. I don't think many people could be funny in those conditions.
I think some people with autism have a brilliant sense of humour. Also I always wondered if John Linnell of TMBG may have aspergers or something, and he has a really quick wit and a cool sardonic/surrealist style of humour.
Plus, many people find actual joke telling hard. Lots of
actual comedians find traditional joke writing hard, and actually go for different kinds of comedy.
I think being funny is a real skill, although it's not talked about as something you can learn. Why don't you get a book on joke-writing, or join a class (if you dare)? Obviously like any art you have to have a creative streak but learning to be funny is actually quite logical I think.
Brilliant! Your punchline was really funny. Perhaps you underestimate your wit.
I might join a class. I usually don't tell many jokes though. I just made a conscious effort to with this thread.
