This is a joke I made up when I heard that people with nonverbal learning disabilities (which I have) do not have a sense of humor.
A guy is flying in a hot air balloon, and he's lost. He lowers himself over a field and calls to a guy "Can you tell me where I am and where I'm headed?"
"Sure. You're at 41 degrees 2 minutes and 14 seconds North, 144 degrees 4 minutes and 19 seconds East; you're at an altitude of 762 meters above sea level, and right now you're hovering, but you were on a vector of 234 degrees at 12 meters per second"
"Amazing! Thanks! By the way, do you have Asperger's Syndrome?"
"I do! How did you know that?"
"Because everything you said is true, it's much more detail than I need, and you told me in a way that's no use to me at all."
"Huh. Are you a clinical psychologist?"
"I am, but how the heck did you know that???!!??"
"You don't know where you are. You don't know where you're going. You got where you are by blowing hot air. You put labels on people after asking a few questions, and you're in exactly the same spot you were 5 minutes ago, but now, somehow, it's my fault!
