- Penny: You came into my apartment last night while I was sleeping?
- Leonard: Yes, but only to clean.
- Sheldon: Really more to organize. You're not actually dirty, per se.
- Penny: Give me back my key.
- [Leonard hands said key back]
- Leonard: I'm very, very sorry.
- Penny: Do you understand how creepy this is?
- Leonard: Uh, yes. We discussed it at length last night.
- Penny: In my apartment? While I was *sleeping*?
- Sheldon: And snoring. And that's probably just a sinus infection. But it could be sleep apnea. You might wanna see an otorhinolaryngologist. The throat doctor.
- Penny: And what kind of doctor removes shoes from asses?
- Sheldon: Depending on the depth, that's either a proctologist or a general surgeon.
- [behind Penny, Leonard holds up a piece of paper with "sarcasm" scribbled on it]
- Sheldon: Oh.
- Sheldon: I am truly sorry for what happened last night. I take full responsibility and I hope it won't color your opinion of Leonard, who is not only a wonderful guy but also, I hear, a gentle and thorough lover.
- Leonard: Do you wanna join us for Thai food and a Superman movie marathon?
- Penny: Wow, a marathon, how many Superman movies are there?
- Sheldon: You're kidding, right?
- Penny: You know, I do like the one where Lois Lane falls from the helicopter and Superman swooshes down and catches her. Which one was that?
- Leonard, Sheldon, Wolowitz: *One.*
- [Raj holds up one finger]
- Sheldon: You know that scene was rife with scientific inaccuracy?
- Penny: Yes, I know men can't fly...
- Sheldon: No, no, let's assume that they can... Lois Lane is falling, accelerating at an initial rate of 32 feet per second per second... Superman swoops down to save her by reaching out two arms of steel... Miss Lane, who is now traveling at approximately 120 miles an hour, hits them and is immediately sliced into three equal pieces.
- Leonard: Unless Superman matches her speed and decelerates.
- Sheldon: In what space, sir, in what space? She's two feet above the ground. Frankly, if he really loved her, he'd let her hit the pavement. It'd be a more merciful death.
- Leonard: Well, excuse me! Your entire argument is predicated on the assumption that Superman's flight is a feat of strength.
- Sheldon: Are you listening to yourself? It is well established that Superman's flight is a feat of strength. It is an extension of his ability to leap tall buildings, an ability he derives from Earth's yellow sun!
- Wolowitz: And you don't have a problem with that? How does he fly at night?
- Sheldon: Uh, a combination of the Moon's solar reflection, and the energy storage capacity of Kryptonian skin cells.
- Penny: I'm just gonna go wash up.
- Leonard: I have 26 hundred comic books in there; I challenge you to find a single reference to "Kryptonian skin cells."
- Sheldon: Challenge accepted!
- [walks to door]
- Sheldon: We're locked out...
- Koothrappali: Also, the pretty girl left.
- Leonard: Do you realize that if Penny wakes up there is no reasonable explanation as to why we're here.
- Sheldon: I just gave you a reasonable explanation.
- Leonard: No, you gave me an explanation; its reasonableness will be determined by a jury of your peers.
- Sheldon: Don't be ridiculous... I have no peers.
- Koothrappali: Hello. Sorry I'm late, but I was in the hallway chatting up Penny.
- Wolowitz: Really? You, Rajesh Koothrappali, spoke to Penny?
- Koothrappali: Actually, I was less the chatter than the chattee.
- Leonard: Did it ever occur to you that not everyone has the compulsive need to sort organize and label the entire world around them?
- Sheldon: No.
- Leonard: Well, they don't. Hard as it may be for you to believe, most people don't sort their breakfast cereal numerically by fiber content.
- Sheldon: I'm sorry, but I think we've both found that helpful at times.
- Penny: Hey Raj.
- [no response]
- Penny: Still not talking to me?
- Sheldon Cooper: Don't take it personally. It's his pathology. He can't talk to women.
- Howard Wolowitz: He can't talk to attractive women, or in your case, a cheesecake-scented goddess.
