Howard: They're not dating. They're just two friends who went out to dinner.
Raj: And then went back to the home they share where they probably fell asleep in the matching pajamas she got them because they both just love penguins.
Howard: Hey, 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.

Leonard: Oh, hey, we ran into your mom at Benihana last night.
Howard: Uh, yeah, she loves that place. Every time they flip a shrimp in the air, she practically leaps out of her seat to catch it. That's why I don't take her to SeaWorld.

Penny: You locked them in your basement?!
Dr. Lorvis: Well, they're, they're not locked in. The door just sticks.

Amy: As a female scientist, I think what you do affects all of us.

Bernadette: Because no one wants to see Neil deGrasse Tyson in a wet T-shirt bent over the hood of a Porsche.

Leonard: He tried to score with Penny.
Sheldon: So have these two, and they're having dinner with us.

Penny

Okay, what's the big deal? Look, if it helps me make a sale with a physician, I don't think it hurts to flirt a little. I mean, laugh at their joke, touch their arm, maybe crank up the AC in the car beforehand, you know, to wake up the girls.

Penny

Penny: I think the message is -- "Check out the rack on that scientist."
