Jon and Amanpreet were in a mental institution. This place had an annual contest picking two of the best patients and gives them two questions. If they got them correct, they’re deemed cured and free to go.
Jon was called into the doctor’s office first and asked if he understood that he’d be free if he answered the questions correctly.
The doctor said, “Jon, what would happen if I poked out one of your eyes?”
Jon 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 Jon’s hand, and told him he was free.
On Jon’s way out, as the doctor filled out the paperwork, Jon mentioned the exam to Amanpreet. He told him what questions were going to be asked and gave him the answers.
So Amanpreet came in. The doctor went thru the formalities and asked, “What would happen if I cut off one ear?”
Amanpreet, remembering what Jon had said was the correct answer said, “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,” Amanpreet answered.
“Amanpreet, can you explain how you’d be *blind*?”
“My hat would fall down over my eyes.”
