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."
