A man is strolling past the mental hospital and suddenly remembers an important meeting.
Unfortunately, his watch has stopped, and he cannot tell if he is late or not. Then, he notices a patient similarly strolling about within the hospital fence.
Calling out to the patient, the man says, "Pardon me, sir, but do you have the time?"
The patient calls back, "One moment!" and throws himself upon the ground, pulling out a short stick as he does. He pushes the stick into the ground, and, pulling out a carpenter's level, assures himself that the stick is vertical.
With a compass, the patient locates north and with a steel ruler, measures the precise length of the shadow cast by the stick.
Withdrawing a slide rule from his pocket, the patient calculates rapidly, then swiftly packs up all his tools and turns back to the pedestrian, saying, "It is now precisely 3:29 pm, provided today is August 16th, which I believe it is."
The man can't help but be impressed by this demonstration, and sets his watch accordingly.
Before he leaves, he says to the patient, "That was really quite remarkable, but tell me, what do you do on a cloudy day, or at night, when the stick casts no shadow?" The patient holds up his wrist and says, "I suppose I'd just look at my watch."
The psychology instructor had just finished a lecture on mental health and was giving an oral test.
Speaking specifically about manic depression, she asked, "How would you diagnose a patient who walks back and forth screaming at the top of his lungs one minute, then sits in a chair weeping uncontrollably the next?"
A young man in the rear raised his hand and answered, "A basketball coach?"
What am I ?
Miss Jones had been giving her second-grade students a lesson on science. She had explained about magnets and showed how they would pick up nails and other bits of iron.
Now it was question time, and she asked, "My name begins with the letter 'M' and I pick up things. What am I?" A little boy on the front row proudly said, "You're a mother!"
