Howard: Can you imagine seeing someone all day long and then you're supposed to hang out with them after work, too?
Raj: Hold on. We do that all the time. You and I work together and play together.
Howard: Yeah, I know, and it drove me into the arms of another woman.

Howard: Wait. Wait. If it wasn't for Indiana Jones, the ark would never have ended up at the warehouse!
Sheldon: (gasps) That's true! He collected and delivered the ark to the proper authorities for filing.
Raj: Like a hero.
All: Yeah! Right! Yes!
Leonard: Although, technically, Indy was supposed to take the ark to a museum to be studied. He couldn't even get that done.
All: Aww.

Sheldon: To the planetarium!
Penny: Let's go!
Leonard: To the Tar Pits!
Bernadette: Let's go!
Amy: There's a Neil Diamond concert next month.
Howard: Let's go!

Howard: No, I am definitely up a cup size.
Raj: You, know, b-but they're very firm, so you've got that going for you.
Howard: You think?
Raj: Yeah. Yeah. Yeah. Very perky.
Howard: Thank you. I really needed to hear that today.

Hey, easy. My nipples are sensitive.

I need you to be honest with me. Do my boobs look bigger to you?

Howard: I feel so stupid. And fat.
Bernadette: That's okay. You still look great to me. In fact, why don't we go in the bedroom and I'll prove it to you?
Howard: Sex? Really? That's just your solution for everything.

Howard: You're full of estrogen and you don't act like that.
Bernadette: That's 'cause I'm a woman. I've had years of practice riding the dragon.

Raj: Why are you on a diet?
Howard: I've put on a couple pounds. I buy these pants in the men's section.
Raj: Well, we've all seen your mom. That Butterball turkey was bound to come home to roost.

Howard: What were they thinking putting Doctor Octopus's mind in Spider-Man's body?
Raj: Well, I've been quite enjoying that. It combines all the superhero fun of Spider-Man with all the body-switching shenanigans of Freaky Friday. Both versions: original and Lohan.
Howard (imitating Raj): "Both versions: original and Lohan."

Howard: There's a party for incoming post-docs tonight. Go to it and meet someone who isn't made of grease or pie.
Raj: You think you're so cool because your wife is a person?

And, space beats water.

TBBT Quotes

Penny: Here's a question-- as an alien pretending to be human, are you planning to engage in any post-prom mating rituals with Amy?
Sheldon: There are post-prom mating rituals?
Penny: Not always. Unless your date drives a van with an air mattress, then always.
Sheldon: Well, if it's part of the prom experience, then I'm open to it.
Penny: You're kidding.
Sheldon: I may be an alien, but I have urges.If Amy wants to copulate by firing her eggs into space, well, then, I will happily catch them with the reproductive sac on my upper flermin. I'm not the best at reading facial cues, but I can see that you're a little turned on.

Raj: Well, to paraphrase Shakespeare: It's better to have loved and lost than to stay home every night and download increasingly shameful pornography.
Penny: Oh... you poor baby.
Raj: What's wrong with me, Penny?
Penny: Nothing, nothing. You know, if we weren't friends - and you hadn't brought up that creepy pornography story - I'd be on you like the speed of light squared on matter to make energy.
Raj: Hey, you totally got that right. E = MC squared.
Penny: I listen. I have no idea what it means, but I listen.
