A man goes into the hospital for some tests. The medical staff knock him out, and when he comes around there is a doctor peering over him, you know pulling up the eyelid and wielding the reflex hammer.

The doctor says, "Ah, I'm glad you're awake. I'm afraid I have some mixed news."

The man says "Don't hold back Doc, tell me the bad news."

The doctor says "It was worse than we thought; we had to amputate your left leg."

The man then asks "What is the good news then?"

The doctor replies, "The man in the next bed wants to buy your slippers."
