The Big Bang Theory, Season 7

Bernadette:
You guys ever thought of getting a dining room table?

Amy:
Yeah, you actually do have room for one up there.

Raj:
Oh sure! I sit on the floor for years, no one cares. The pretty white girl sat 10 seconds and suddenly we're all running to IKEA.

Sheldon:
No one is running anywhere. We're not getting a dining room table.

Leonard:
I know you don't like change, but it's not a terrible idea.

Penny:
You guys never use that space up there. Why not get a table?

Sheldon:
Do you want the long answer or the short answer?

Howard:
How come we never get that option?

Sheldon:
Chaos theory suggests that even in a deterministic system if the equation is describing its behavior in non-linear, a tiny change in the initial conditions can lead to a cataclysmic and unpredictable result.

Penny:
Translation?

Leonard:
[Imitating a baby] Wah! I don't want a table!
