A visitor to a mental institution asked the director how it was decided which patients should be kept in and which were ready to be discharged.

The director said:  “Well, we fill up a bath, then offer the patient a teaspoon, a teacup or a bucket and ask them to empty the bathtub”.

The visitor said, “Oh, I see, and of course a normal person would chose the bucket because it’s the biggest”.

The director said: “No! A normal person would pull the plug out.”

“Would you like a bed near the window?”
