Aside from it being off-topic, what in the world does that have to do with ADHD? Strict rule-following and inability to understand idioms is stereotypically (and of course often inaccurately) associated with autism, not ADHD. A proper joke about ADHD would be something like,
Why did the person with ADHD bring a ladder to the bar?
Because they were trying to fix a light that went out and they'd fixed it after they put their phone somewhere far away so they couldn't get distracted but then they remembered that they had to go get the groceries so they did - well, some of it anyway, they forgot a fair amount of the things they were supposed to get - and then they remembered they'd forgotten about the ladder so they went back to put it away and right after they'd started hauling it away, they remembered that they were supposed to meet with some friends at the bar so they went to the bar.
It's not a very good joke, of course (listen, coming up with jokes on the fly is hard!) but it's much better. ChatGPT can't even get its stereotypes right.
(It is interesting that it used 'they' for the person. I'm all for it, but I was expecting it to use 'he', as that presumably comes up more than they in conversation/jokes.)
