Howard: If there's a chance someone's gonna see you naked, it's also polite to make sure you're well-groomed down there.
Bernadette: I get it, Howard. I've been busy!

Howard: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Howard: Settle this. Those little animated pictures on the Internet, are they called "gifs" or "jifs"?
Leonard: Well, the G stands for "graphics." That's a hard G, so I'd say "gif."
Raj: What? The guy who invented it says it's "jif."
Howard: I'm sorry, do you mean the guy or the juy?

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

Amy: Well, Leonard and Penny are our best friends. They know us better than anyone. They said it's the perfect gift. We must be missing something. You don't think it's a marital aid, do you?
Sheldon: Don't be silly. Amy, how is this big glass shaft going to aid our marriage?

Amy: Let's just go to sleep. We'll look at it in the morning with fresh eyes, and maybe it'll come to us.
Sheldon: Fine.
Amy: Or we go tear apart that box and look for a clue.
Sheldon: Staying up past my bedtime and solving mysteries? Who knew married life could be this good?

Sheldon: Howard, I don't often say this, but, good, you're here.
