During a visit to the mental asylum, a visitor asked the
director, "What is the criterion that defines a patient to be
institutionalized?"
"Well..." said the director, "we fill up a bathtub, and we offer a
teaspoon, a teacup, and a bucket to the patient and ask him to
empty the bathtub."
[Pause and think] How would you empty
the bathtub in this situation? (Highlight the below sentences to
continue reading the conversation between the director and the
vistor.)

"Oh, I understand," said the visitor.
"A normal person would choose the bucket as it is larger than the
spoon or the teacup."
"Noooooooo!" answered the director. "A normal person would pull the
plug."

to tell anyone how you would have done on this test.)
