Leonard: Sometimes change is good. You were worried about Zachary Quinto being the new Spock, but you ended up liking him.

I'm upset daylight savings time started -- Zachary Quinto. I'm upset daylight savings time ended -- Zachary Quinto. I'm saying this for the last time. Zachary Quinto was a weird, wonderful, unrepeatable event, so stop using him against me.

Howard: What a sick use of science.
Raj: Hey, as long as the baby's healthy.
Amy: I wonder if Stalin considered any other animals.
Leonard: Hippos are the deadliest creature. A half-human, half-hippo soldier would be pretty badass.
Howard: Yes, but when they're hungry-hungry, you can stop them with marbles.
Sheldon: Yeah, the correct animal for interspecies supersolider is koala. You would wind up with an army so cute it couldn't be attacked.

Nathan Fillion: How about a guy who looks like Nathan Fillion, but a little more annoyed than Nathan Fillion usually is?
Leonard: What do you think?
Raj: Aww. That's good enough for Facebook.

Sheldon: That is literally the stupidest thing I've heard.

Penny: Think we'll have time to visit your mom while we're there?
Leonard: Yes. We'll also have time to put my junk in a garlic press, but I'm not doing that either.

Sheldon: I should have brought an umbrella.
Leonard: What for? It's not gonna rain.

Sheldon: It's not a present. It's the present. There's you and me. It's Penny and Amy. We're playing Pictionary. In the present.
