Raj: So, what are you guys doing later? Stuart and I were thinking of going out for a drink.
Stuart: We're gonna try to meet some girls.
Raj: 'cause that's what we do.
Stuart: Watch out, ladies, a little coffee and cream coming your way.
Raj: In case you didn't follow that, I'm the coffee.

Sheldon: Do you remember how upset I was when they replaced Edward Norton as the Hulk?
Leonard: Yes, you walked around for a week saying, Sheldon unhappy with casting choice.
Sheldon: But, then Mark Ruffalo was the Hulk in The Avengers, and he was even better.
Leonard: What's your point?
Sheldon: Call me a romantic. I like to think that your Mark Ruffalo is still out there somewhere.

Penny: Look, it's fine. We're not getting married, okay? We're keeping things, you know, homeostasis.
Amy: It's so cute when she tries.
