Leonard: Stephen Hawking’s team is looking into that, and I’ve been invited to join them.

Penny: wow, Hawking! Good for you!

Leonard: well it is. Just, you know, I would be gone for a while.

Penny: well, how long?

Leonard: three four months.

Penny: woo, when would you leave?

Leonard: couple weeks.

Penny: okay, well, I’ll just come visit you.

Leonard: that’s the thing. You can’t. I’ll be on a ship in the North Sea.

Penny: on a ship? Aren't they afraid hawking will just roll overboard?

Leonard: uh, he is not gonna be there. He’s just sending a team to research his theory.

Penny: oh sure. Like when you send me to kill spiders in your bathtub [bæθtʌb]. Okay, four months.

Leonard: yeah. And I’m a little worried, because things between us have been so great, and I would hate to do anything that screws that up.

Penny: oh, sweetie, if you’re gonna screw things up, it’s gonna be while you’re here, not while you’re away. No, I mean, look, you have to go. It sounds like an amazing opportunity. And I’m just basing that on how much I didn't understand what you said about it.

Leonard: okay. I’ll confirm the travel arrangements [ə'rendʒmənt] in the morning.

Penny: okay, good.

Leonard: I do have to ask you one favor.

Penny: sure.

Leonard: Sheldon is nervous about me leaving. Just keep an eye on him while I’m gone.

Penny: oh, I don't know. Remember what happened when I took care of your goldfish?

Leonard: well flush [flʌʃ] Sheldon down the toilet and get me a new one.
