A few days before his proctological exam, a one-eyed man accidentally swallowed his glass eye. He was worried for a while, but there were no ill effects, so he forgot about it.

Once he was in the doctor's office, the man followed his instructions, undressed and bent over. The first thing the proctologist saw when he looked up the man's butt was that glass eye staring right back at him!

"You know," said the doctor, "you really have to learn to trust me."
