Teaspoon, TeaCup or Bucket?

During a visit to the mental asylum, a visitor asked the Director which is the criteria that defines a patient to be institutionalized.

"Well," said the Director, "we fill up a bathtub, we offer a teaspoon, a teacup, and a bucket to the patient and ask the patient to empty the bathtub".

Okay, here's your test:

1. Would you use the spoon?

or

2. Would you use the teacup?

or

3. Would you use the bucket? "

Oh, I understand," said the visitor. "A normal person would choose the bucket as it is larger than the spoon or the cup."

What do you say?  Is that right?
