Sheldon: It's great you're here. I'd love to get an engineer's opinion.
Howard: Sure.
Sheldon: This chair is squeaky. Now, do I fix it or get a new one?

Look who's here to put the Jew in jewelry night.

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.

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."

Penny: Hey, Sheldon, did you change your Wi-Fi password again?
Sheldon: Yes, it's "Penny, get your own Wi-Fi." No spaces.
