The blonde sits down before the eye doctor explaining she's losing her sight. He sets up the eye chart, but she tells him she can't even see it.

"Well, he asks, "can you count the number of diplomas on the wall?"

"No," she responds, "too blurry."

So he unzips his fly and pulls out his pecker and asks, "can you see this?"

"Yes," she replies, "that's your penis!"

"I knew it," says the Doc, "you're cockeyed!"
