Female Passenger: “So, what kind of work do you do?”

Male Passenger: “Oh, well I run an institution.”

Female: “You mean like a mental institution?”

Male: “Sort of.”

Female: “What’s wrong with your patients?”

Male: “Well, they’re mostly delusional. They labor under the impression that they have immense powers to control one of the most complex systems on earth.”

Female: “Ah, I see. So, they’re intellectually challenged?”  

Male: “Oh, no. Quite the contrary. Most of them hold PhDs. They’re an extremely intelligent group. Just a bit delusional.”
