Leonard: Come on, Sheldon. It will be fun.
Sheldon: That's what you said about the Green Lantern movie. You were 114 minutes of wrong.

Leonard: What are you doing?
Amy: We're playing doctor. Star Trek style.
Sheldon: I'm in hell, Leonard. Don't stop.

Leonard: I got you that book last year, wasn't everything in there?

I love strawberry Quik. It's my favorite pink fluid narrowly beating out Pepto-Bismol.

I look like the Flash about to be married.

A little. But not more than your urethras will be after whatever's in those pants swims up them.

Raj: Oh, oh, what about the tubby girl in the Sailor Moon costume at Comic-Con?
Howard: Don't remember. Please sit down.
Raj: The only threesome I've ever had in my whole life and I'm proud to say it was with this man right here.
[All laughing]
Raj: Oh, oh, don't get me wrong, nothing happened with me and Howard. There was about 200 lbs of Sailor Moon between us.
Wil [recording on his phone]: Oh, Internet, this is so going all over you.

Stephen Hawking: I know.

Howard: No ... about my job. I want you to tell me I'm good at what I do.
Sheldon: You're obviously good at what you do.
Howard: Well, then why are you always ripping on me?
Sheldon: Oh, I understand the confusion. I have never said that you are not good at what you do, it's just that what you do is not worth doing.

Howard's mother: It's this dress. When I put my front in, my back pops out. When I put my back in, my front pops out. It's like trying to keep two dogs in a bathtub.
Sheldon: What do you want me to do?
Howard's mother: We're going to have to work as a team. Get in here, grab a handful and start stuffing.
