Mental institution

Darryl and Harold were in a mental institution. The place had an unusual annual contest, picking two of the best
patients and giving them two questions. If they got them correct, they were deemed cured and free to go.

Darryl was called into the doctor's office first and asked if he understood that he'd be free if he answered the
questions correctly. Darryl said "yes" and the doctor
proceeded. "Darryl, what would happen if I poked out one
of your eyes?"

Darryl said, "I'd be half blind."

"That's correct. What if I poked out both eyes?"

"I'd be completely blind." The doctor stood up, shook
Darryl's hand, and told him he was free to go.

On Darryl's way out, as the doctor filled out the paperwork, Darryl mentioned the exam to Harold, who was seated in the waiting room. He told him what questions were going to be asked and gave him the answers.

So Harold went into the doctor's office when he was
called. The doctor went thru the formalities and then
asked, "What would happen if I cut off one of your ears?"

Remembering what Darryl had told him, he answered, "I'd
be half blind."

The doctor looked a little puzzled, but went on. "What if I cut off the other ear?"

"I'd be completely blind," Harold answered.

"Harold, can you explain how you'd be blind?"

"My hat would fall down over my eyes."
