I have to hit the head. That's what us salty seadogs say when we have to go pee-pee.

Leonard

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."

Don't try to trick me into buying something I don't want. Now, let's talk Aquaman.

Sheldon

Leonard: I didn't tell Sheldon so we could have a few days alone.
Penny: Oh, that is so romantic.
Leonard: Uh, sure, that's why I did it.

Now, I know how you felt getting mauled by that sex-crazed gorilla.

Sheldon

Sheldon: Well, if it's any consolation, i'm sure Leonard's tormented every moment he's away from your warm embrace and cherry lips.
Penny: Thanks.
Sheldon: Oh, seriously?

Penny: You know what the worst part is?
Sheldon: That you're having to process your emotional pain without vodka?
Penny: No. Yeah....

Your husband's weird and his clothes are ridiculous.

Amy

Penny: I cannot believe we were missing that jerk.
Sheldon: You were.

Penny: I'm calling him.
Sheldon: Oh, goodie! Put him on speaker phone.

Guys are hitting on us and not just to get to Penny.

Amy

The Big Bang Theory Season 7 Quotes

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?

Sheldon: Even the dung beetle chooses to plot its course by using the Milky Way.
Raj: Is that true?
Sheldon: Everything I say is true. Now, of course, the dung beetle also enjoys eating fece, living in feces and making little balls out of feces. So, pick and choose which aspects of its lifestyle you want to embrace.
