Two men are in a hot-air balloon. They drift into a dense cloud bank and are stuck there for hours. Finally as they emerge they look around at the ground below in hopes of figuring out their location.
They see a man in a garden and shout down to him.
"Hello down there! Can you tell us where we are?"
"The man below replies, "You're in a hot-air balloon."
The first man looks at his partner and comments, "Just our luck, a psychologist."
The partner asks, "Why do you say he's a psychologist?"
The first man answers, "Well, what he said was obviously true, but it didn't help at all."
