Mr. Johns goes to the doctor

Mr. Johns goes to the doctor for a check up.

After extensive tests the doctor tells him, “I’m afraid I have some bad news for you. You only have six months to live.”

Mr. Johns is dumbstruck.

After a while he replies,

“That’s terrible doctor. But I must admit to you that I can’t afford to pay your bill.”

“OK,” says the doctor, “I’ll give you a year to live.”
