It's Always Sunny in Philadelphia, Season 3

Charlie:
[singing] They took you, Night Man, and you don't belong to them. They left me in a world of darkness without your sexy hands, and I miss you, Night Man, so bad... [hits piano, starts mumbling] stupid! Can't write anything. [huffs spray paint]

Dennis:
[Enters Charlie's apartment without knocking] Charlie, let's join forces.

Charlie:
Hello, come right in!

Dennis:
I will.

Charlie:
What happened to your band?

Dennis:
Kicked me out.

Charlie:
[laughs] Well, it hurts, doesn't it?

Dennis:
Hm. What's with the curtains?

Charlie:
I'm living in a world of darkness.

Dennis:
Right. Let's get some light in here. [pulls curtains off, filling room with light, notices Charlie's face] Whoa, what's with the spray paint, man?

Charlie:
Uhh...what's with your outfit man? [Dennis is wearing spandex]

Dennis:
Why don't we put the curtains back up...

Charlie:
No, no...what is going on up here, man? [laughing]

Dennis:
I never know, man.
