Rescue Me, Season 3

Sean:
You know what, Tom, this is just you -- being you, y'know, overprotective and thinkin' I'm good enough for your sister.

Tommy:
That is not the issue believe me.

Sean:
Yes it is.

Tommy:
Of course you're good enough for her.

Sean:
Oh, really?

Tommy:
Yeah. And so are the four other guys, the underwear and the sock guys.

Sean:
Oh, very funny. [they get into a shoving match]

Tommy:
My sister.

Sean:
She's my girlfriend! [Sean starts walking away]

Tommy:
And well, one other thing, asshole.

Sean:
What?

Tommy:
Don't tell her I mentioned this stuff to you, alright? Please? Sean?
