Amy: That's very nice of you, but I do have a boyfriend.
Bert: That's what you all say. You just don't want to go out with me because I have an off-putting personality.
Amy: No, that's not true. My boyfriend has an off-putting personality, too. Like, way worse than you.
Bert: Don't worry. I'm used to it. I mean, I'm big and weird and funny-looking and no one ever wants to do anything with me.

Sheldon: I've been modeling different types of dark matter and the traces they would leave on the zircon inside your meteorite.
Bert: What's this one here?
Sheldon: That's actually a dark matter model of my own creation. I call it the Cooper Boson.
Bert: Cool. I got to name a rock once. I named it Moderately Sedimented Shale. Guess I kind of pooped the bed on that one.

Bert: I met her on G-Harmony. That's a Web site for geologists to find love.
Amy: That's a real thing?
Bert: Yeah. Their slogan is "We're all about dating and not the carbon-14 kind".

Bert: I don't really have dreams, when I sleep or in life.

Penny: Thank you, I needed to hear that. Why can't Leonard understand it?
Sheldon: Because he's not like us, Penny. We're dreamers!
Penny: Yeah, I need to start cracking the window when I leave you in the car.

Bernadette: Hey, Stuart.
Stuart: *startled* Hey.
Bernadette: Sorry, did I startle you?
Stuart: Yes, but at this point pretty much any customer does.

Jesse: You're back.
Bernadette: *Angry voice* Yes, I am. There's a few more things I want to say to you. Stuart's store is just fine. And he's a much nicer person than you are. And if you still have that comic I'd like to buy it right now.
Jesse: No problem. Want a latte while you wait?
Bernadette: No, I don't want a latte. I want a cappuccino and a blueberry scone.
Jesse: I only have chocolate chip.
Bernadette: Well that sounds even better!
