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.
