The Big Bang Theory, Season 3

Sheldon:
What are they doing here?

Leonard:
We came to apologize again and bring you home. So why don't you pack up your stuff, and we'll head back?

Sheldon:
No, this is my home now. Thanks to you, my career is over, and I will spend the rest of my life here in Texas trying to teach evolution to creationists.

Mrs. Cooper:
You watch your mouth, Shelly. Everyone's entitled to their opinion.

Sheldon:
Evolution isn't an opinion, it's fact.

Mrs. Cooper:
And that is your opinion.

Sheldon:
[to the guys] I forgive you, let's go home.

[Sheldon leaves to pack]

Mrs. Cooper:
[smiling] Don't tell me prayer doesn't work.
