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.

Leonard: What would you be if you were attached to another object by an inclined plane, wrapped helically around an axis?
Sheldon: Screwed?
Leonard: There you go.

Sheldon: This song is never going to stop. Have you ever dealt with something so relentlessly irritating?
Leonard: That's a trick question, right?

Leonard: Penny, as a scientist, my job is to figure out why things happen. But I don't think I'll ever understand how someone like me could get to be with someone like you. You know maybe I don't need to understand it, I just need to be grateful. I love you, Penny.

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.
