A young woman visited her eye doctor complaining of failing eyesight. The doctor sat her in front of a standard eye chart.
Doctor: Can you read the bottom line?
Girl: No.
Doctor: Can you read the center line?
Girl: No.
Doctor: Can you read the large top line?
Girl: No.
Doctor: Can you even see the chart?
Girl: No.
The doctor is clearly frustrated and whips his penis out of his pants. Can you see this?
Girl: Of course!
Doctor: Well, there's your problem - you're cock-eyed!
