It's Always Sunny in Philadelphia, Season 3

Dee:
Well, I just broke up with Kevin!

Mac:
Dee, we're trying to practice!

Dee:
I can't do it! I can't get it out of my head! I don't know if he's retarded or not, but I can't stop thinking about it!

Dennis:
Dee, we're trying to have band practice here!

Dee:
I mean, I was gonna ride this guy to the top, you know what I mean? He was gonna put me in one of his rap videos!

Dennis:
Look, the guy's not retarded, okay?

(beat)

Dee:
What?!

Dennis:
Yeah, I was just saying that to mess with you.

Dee:
Why? Why would you do something like that?

Dennis:
I thought it'd be funny.

Dee:
It's not funny! It's not funny at all! This guy's perfect for me, and you've gone and blown it! You've ruined everything! You are a bad, bad person.

(points at Dennis' jumpsuit)

Dee:
Ewww, (trounces out)

Dennis:
All right! Ready, guys?

Mac:
So, that guy's not retarded?

Dennis:
Oh no, he's totally retarded.
