Sheldon Cooper: Dad, do you believe that fossils are millions of years old?

George Cooper Sr.: I guess. Why?

Sheldon Cooper: Well, Mom believes the world was only created 6,000 years ago.

George Cooper Sr.: Yeah. So?

Sheldon Cooper: Are these differences a sticking point in your marriage?

George Cooper Sr.: Not at all.

Sheldon Cooper: Why?

George Cooper Sr.: Simple. We never talk about it.

Sheldon Cooper: So you just avoid discussing topics you don't agree on?

George Cooper Sr.: At all costs.

Sheldon Cooper: Hearing that further convinces me I'll never get married.

George Cooper Sr.: Never say never.

Sheldon Cooper: Why not? You just said it twice.
