Penny: Okay, well, what about Reiki? It's like massage but without touching.
Sheldon: Then what is it?
Penny: Well, I place my hands near your body and allow the universal energy field to manifest its healing powers. Okay, I know it sounds crazy, but it really works; ask Leonard.
Leonard: It really does.
Penny: Yeah.
Leonard: [mouths] No.

Sheldon: I remember the song! It's called "Darlin'" by the Beach Boys! Oh, thank goodness! I'm not crazy! I don't have to take a pigeon as my bride!
Leonard: There goes our shot at him living on the roof.

Howard: Don't feel bad. Some day someone will be throwing out your work, too.
Leonard: That someone was Sheldon and the day was yesterday.

Professor Proton: Can I ask you a question?
Leonard: Yeah, sure.
Professor Proton: Why do you put up with Sheldon?
Leonard: Oh, you know because we're friends.
Professor Proton: Why?
Leonard: Wow, you ask really hard questions. Look, I know he can be aggravating, but what you have to remember is he's not doing it on purpose, it's just how he is. But he's also loyal and trustworthy and we have fun together.
Professor Proton: You know you're describing a dog?
Leonard: He did bite me once. But in his defense, I came up behind him while he was eating.
Professor Proton: They hate that.
Leonard: Sheldon is the smartest person I have met. He's a little broken and he needs me. And I guess I need him too.
Professor Proton: Why is that?
Leonard: Boy, you will not let this go, will you?

Bernadette: Why do you want to ride that stupid thing anyway?
Howard: I don't know. Maybe I just miss the freedom I had as a younger man.
Bernadette: What freedom? You lived with your mother. You had a curfew.

Howard: This is a twist. Usually you're the one getting called into H.R.
Raj: Yeah, now it's Amy. Who knew you were married to such a bad girl.
Sheldon: I suppose the signs were always there. I mean, she did recently go to that rave at the mall.
Amy: It was a Spencer's Gifts.
Sheldon: There was music and a strobe light. If that isn't a rave, then I don't know what one is.
Leonard: You don't know what one is.

Amy: Guys, come on, I think I'm in trouble.
Howard: It's no big deal. I used to get called into H.R. all the time. Ms. Davis is great. Pro tip: if you find strong women sexy, do not say it out loud.
