Dr. David Underhill
- Penny: How do you know Leonard?
- Dr. David Underhill: I'm a physicist.
- Penny: [laughing] No, you're not.
- Dr. David Underhill: Why is that so surprising?
- Penny: Well, it's just that the physicists I know are indoorsy and pale.
- Leonard Hofstadter: I'm not indoorsy. I just wear the appropriate sunblock because I don't take melanoma lightly.
- Leonard Hofstadter: So, um, Dave, don't you think you and I should get back to the lab? You know, that dark matter isn't going to detect itself.
- Dr. David Underhill: Actually, I was thinking about taking the afternoon off so I could work on another experiment with Penny.
- Penny: Really? We're, we're going to do an experiment.
- Dr. David Underhill: Uh-huh, we're going to explore the effects of tequila shots on a gorgeous 22-year-old woman.
- Penny: [laughs] That's not an experiment; you saw what happened last night.
- Dr. David Underhill: So you and her...
- Leonard Hofstadter: No, just neighbors.
- Dr. David Underhill: Really? I don't know how you live next door to that without doing something about it.
- Penny: Ooo, are you okay?
- Leonard Hofstadter: Oh yeah, it's just a little motorcycle accident.
- Penny: My God, how fast were you going?
- Leonard Hofstadter: I don't know, it's all such a blur.
- Dr. David Underhill: [laughs] Good one. He couldn't even get it started. Hi, Dave.
- Penny: Hi, Penny. Your motorcycle?
- Dr. David Underhill: Uh huh.
- Penny: Oh, is it okay?
- Leonard Hofstadter: Lucky for the bike, it landed on my leg.
