The Big Bang Theory, Season 5

Amy:
Sheldon, what are you doing here?

Sheldon:
The thought of you sitting in a darkened theater with a character like Stuart is repellent. No offense Stuart!

Stuart:
None taken. Though, repellent, is kind of, kind of a strong word.

Amy:
Um... sorry this causes you discomfort but based on the currently established parameters of our relationship, I can put myself in any repellent situation I want.

Stuart:
Um... again...

Sheldon:
Stuart please, you're being rude.

Amy:
Anything else?

Sheldon:
I believe, I would like to alter the paradigm of our relationship.

Amy:
I'm listening.

Sheldon:
With the understanding that nothing changes whatsoever, physical or otherwise. I would not object to us no longer characterizing you as not my girlfriend.

Amy:
Interesting... Now try it without the quadruple negative.

Sheldon:
You're being impossible!

Amy:
Hi, Stuart.

Sheldon:
Fine! Amy, will you be my girlfriend?

Amy:
Yes!

Sheldon:
Alright, that's enough about it. Sorry to interrupt. You two enjoy your date!
