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

The doctor says: "Ah, I'm glad you're awake. I'm afraid I have some good news and some bad news."

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

The doctor says "Your condition was worse than we thought and we had to amputate both of your legs."

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

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