Howard: Lots of people wear matching pajamas who aren't dating.
Raj: Like who?
Howard: Like you and your dog.
Leonard: Don't rule out the dating.

Sheldon: Sorry, kid, you got it worse than a gibbon.

Penny: That, believe it or not, is my prom dress.
Bernadette: Wow, you still have it? I just assumed it was balled up in a corner of a barn somewhere.

Penny: What kind of teenager did you think I was?
Bernadette: Slutty.
Amy: Easy.
Penny: The word is 'popular'.

Bernadette: How was your prom? Did you go?
Amy: No, but I was on cleanup crew.
Penny: Aw, that's sad.
Amy: No, it was okay. The DJ let me dance one slow dance with my mop before he shut down. Whenever I see a bucket of dirty water, I still hear Lady in Red.

Leonard: Wow, Donkey Kong. This was my game when I was a kid.
Sheldon: Because it's a story of a pretty blonde girl tirelessly pursued by a small oddly-shaped man?

Raj: Maybe he's playing bingo with his mommy?
Howard: Sad how some guys just can't cut the apron strings.
Raj: Okay, now you're messing with me.

Penny: Doc, you've got see what you're doing is a little creepy.
Dr. Lorvis: You sound just like Sigourney Weaver when I followed her into a restroom.

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.

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.

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.

Dr. Lorvis: Can I ask you a question? You're a guy like me, how'd you get a girl like Penny?
Leonard: Well, just being myself really.
Sheldon: Oh please. I'll tell you how he did it. Implacable relentless badgering. In urology terms, he was a drug-resistant staph infection and she was a urethra that could not shake him.
Leonard: I don't know that I'd call myself an infection.
Howard: A gallant man would defend his fiance for being called a urethra.

Sheldon: Leonard, I was wrong. Heaven does exist. And it's in the basement of a urologist's house in Sherman Oaks.

Dr. Lorvis: Welcome to my fortress of solitude. This is where I go to get away from all my other solitude.

Howard: Still lives with his mom? Yikes, right?
Raj: Yeah, I'm not quite sure how to respond.
