The Big Bang Theory2007

Leonard Hofstadter:
Relax, it'll be fine. Sit down, you guys.

Leonard Hofstadter, Penny, Raj Koothrappali:
[as Bernadette goes for Sheldon's spot] No!

Bernadette:
What?

Penny:
Oh, yeah. You can't sit there.

Bernadette:
Why not?

Leonard Hofstadter:
That's where Sheldon sits.

Bernadette:
He can't sit somewhere else?

[from across the room Sheldon turns, stares and raises an eyebrow a freakishly long way]

Penny:
Oh, no, no. You see, in the winter that seat is close enough to the radiator so that he's warm yet not so close that he sweats. In the summer, it's directly in the path of the cross breeze created by opening windows there and there. It faces the television on an angle that isn't direct so he can still talk to everybody, yet not so wide that the picture looks distorted.

Sheldon Cooper:
Perhaps there's hope for you after all.
