People, we are now the popular girl at the dance.

Marcus

Call me a romantic. I like to think your Mark Ruffalo is still out there somewhere.

Sheldon

Stuart: Watch out ladies: a little coffee and cream coming your way.
Raj: In case you didn't follow that, I'm the coffee.

Your desperate need for friendship makes you weak.

Sheldon

Penny: We're keeping things, you know, homeostasis.
Amy: It's so cute when she tries.

Sheldon: Penny? Please don't hurt my friend.
Penny: That is the last thing I want to do.
Sheldon: Thank you.

Leonard: The guy who seems like an emotionless robot ... is you, but your relationship with Amy is causing you to transform into a red-blooded man with sexual desires.
Sheldon: That is literally the stupidest thing I've heard.

Sheldon: Wolowitz when to MIT. What's your educational background?
Stuart: I went to art school.
Sheldon: Equally ridiculous. Let's go.

Whenever I'm around Sheldon, I feel like my loins are on fire. In the good way. Not in the urinary tract infection way.

Amy

Kyle: How can you sit there and collect money on a show about a fat child killing himself? Where's your sense of shame?
Token: I can remember exactly where I was the first time I saw Honey Boo Boo. I couldn't believe what I was seeing. A shameful, fat family eating white-trash food, to their deaths? And then I saw what network it was on: The Learning Channel. If they can feel okay about that, why can't I?

James Cameron doesn't do what James Cameron does for James Cameron. James Cameron does what James Cameron does because James Cameron is James Cameron!

James Cameron

Kyle: I've been thinking. How did shamelessness get to this? Did it start with fat people on scooters? Or did it start way before that? And then I started thinking: maybe it was us. I don't know, but maybe somehow we lowered the bar, a long time ago, And now we're all sitting here, in the stink of it all. There's no going back, Stan.
