Howard: How'd you get that?
Dr. Lorvis: Easy. Gene Rodenberry needed a vasectomy.
Sheldon: You've snipped Gene Rodenberry's vas deferens?
Dr. Lorvis: Yes.
Howard: Wow, you really went where no man has gone before.

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Penny: You locked them in your basement?
Dr. Lorvis: Well, they're not locked in. The door just sticks.
Penny: Okay, so how do they unstick it?
Dr. Lorvis: They'd need the key.

Penny: Okay, you can't just go chasing after every girl who's nice to you.
Dr. Lorvis: Well, that's not what Sheldon says, and he seems to know his way around the ladies.

Leonard: Wow, Donkey Kong. This was my game when I was a kid.
