In-flight Announcement: The Captain has turned off the fasten seatbelt sign. You're now free to move about the cabin.
Howard: It's over.
Sheldon: Yeah.
Howard: Should we stop holding hands now?
Sheldon: In a minute.
Howard: Okay, good.

Howard: How do I know what you said? Damn you and your noise-cancelling breasts.

Howard: Hey, she's my wife. If anyone's gonna make her feel gross about sex, it's me.

Penny: You know, my aunt changed her diet and in a few months -
Howard: Went to space? I don't think so! Now pass the soy sauce. Not the green one, the red one.

Howard: What's going on?
Bernadette: Maybe you should have a seat.
Howard: I know my mom's not dead, there'd be balloons.

Howard: Hey. Good news, somebody in this room gets to take a ride on a rocket.
Bernadette: Fine. Can I at least shower first?
Howard: No, not that. Although you already agreed to it, so no takebacks.

Raj: This (wand remote control) might be my second favorite brown magic wand.
Howard: Well, that's the last time I play with that.

Penny: You guys never use that space up there. Why not get a table?
Sheldon: Do you want the long answer or the short answer?
Howard: How come we never get that option?

Sheldon: In what world is a 4-4-6-4 a 4-10-4?
Howard: A world I don't want to live in. (To Bernadette) Seriously, I no longer I want to live in this world.

Howard: You okay?
Amy: Why? Because my boyfriend's off playing choo choo with some weirdo.
Howard: Well, to be fair, they're both weirdos.

Bernadette: So your boyfriend's a fixer-upper? Most of them are. I mean look at this guy. You think he came like this? When I met him he was a hot, goofy mess. Now, he's been to Space. That's all me!
Howard: I had a little to do with it.
Bernadette: Oh sure you did. Who's momma's big Space Man?
Howard: I am!

Amy: (About Sheldon) Why do I even try?
Bernadette: I'm going to fix this right now.
Howard: Okay, but just make it look like an accident.

Howard: Fun Fact: I'm going to jump off this train!

Raj: How are you going to get James Earl Jones?
Sheldon: Simple. Earlier today he tweeted that he's looking forward to going to his favorite Sushi restaurant for dinner. I googled an interview from four years ago, which was conducted in his favorite Sushi restaurant and that's where he'll be. And that's where I'm going. And that's -
Howard: And that's where Darth Vader is going to pour soy sauce on your head.

Sheldon: I can't believe we wasted all that time on our Hulk costumes.
Penny: You were all going as the Hulk?
Howard: Not the same Hulk. Ferrigno, Bana, Norton and Ruffalo.
