Amy: Jewelry? Seriously? Sheldon, you are the most shallow, self-centered person I have ever met. Do you really think that another transparently manipul... Oh! It's a tiara! A tiara. I have a tiara! Put it on me, put it on me, put it on me, put it on me, put it on me, put it on me, put it on me.
Penny: You look beautiful
Amy: Of course I do. I'm a princess and this is my tiara.
Sheldon: You were right, the tiara was too much.

visual: Howard performs a magic trick.
Rajesh: I’m telling you, dude, there’s a seat on the Hogwarts Express with your name on it!

Sheldon: (playing a video game) I think I’ll just go in this saloon and drink my troubles away.
Leonard: You know digital alcohol is never a solution.

Sheldon: (still playing the video game) I’m gonna have a whiskey, do you want anything?
Leonard: No I can’t, I’m playing Grand Theft Auto later.

Sheldon: I don’t think there’s anything in this jewelry store that Amy would appreciate more than the humidifier we were just looking at at Sears.
Penny: Oh my god. Now I know what I sound like to you when I say stupid stuff.

Howard: Maybe me and Bernadette aren’t right for each other.
Leonard: Look, Howard, I’d say there’s a lot of fish in the sea, but I watched you dangle your hook in the water for years. Do not throw her back!
