Good News / Bad News

This old man visits his doctor and after a thorough examination, the doctor tells him, "I have good news and bad news, what would you like to hear first?"

Patient: Well, give me the bad news first.

Doctor: You have cancer, I estimate that you have about two years left.

Patient: That's terrible! In two years, my life will be over! What kind of good news could you probably tell me, after this?

Doctor: You also have Alzheimer's. In about three months you are going to forget everything I told you.
