The Big Bang Theory, Season 3

Leonard:
Hey, where've you been?

Sheldon:
I was talking with Penny.

Howard:
What's wrong with you? You can't hang out with your roommate's ex. That's totally uncool.

Leonard:
No, it's fine. I don't care. I'm over it.

Raj:
Yeah, he's over it; that's why he's been whining all day about trying to invent that memory-wiper gizmo from Men in Black.

Sheldon:
Is he making any progress? Because I'd like to erase Ben Affleck as Daredevil.

Howard:
[to himself] So would Ben Affleck. [to Sheldon] The point is, in a situation like this, you gotta pick sides. You're either on Team Leonard or Team Penny.

Sheldon:
Which one picks last?

Howard:
What?

Sheldon:
Usually, I'm on the team that picks last... unless there's a kid in a wheelchair.
