Law & Order, Season 5

[In interrogation with Mr. Barclay and his son.]

Mr. Barclay:
I guarantee you, it was Harrigan that put him up to it. He and his father, they're all alike, with their Irish temper, they lose control, and the next thing you know, you have a murder--

McCoy:
Oh, so Harrigan did it because he's a Mick? Detective Logan is a Mick. I'm a Mick, sir. And if you don't shut up, I'll lose control and throw you out of the room!
