Becoming a Communist

A man goes to the doctor for a checkup. After the checkup, the doctor tells the man he has bad news:

- You only have six months to live.

The man sits for a while thinking, and then says:

- There's only one thing I can do, I'm going to become a Communist.

The doctor asks:

- You've been a patriotic American all your life, why are you going to become a Communist now?

The man says:

- Better one of them should die than one of us!
