Quon Le: How can anyone relax at a time like this?
Dan: Well, one sure way involves a pound of Velveeta and a copy of True Detective magazine.

Christine: Boy, this place sure has changed since Mac left.
Roz: Yeah. It's the first time in my life I ever had paper cuts on my ankles.

Mac: (behind Dan, patting him on the shoulder) Fielding!
Dan: (jumping) Your wife's lying! I don't even own a saddle!

Roz: (opening present from Mac) I get to see Mike Tyson at Madison Square Garden?
Quon Le: No, you get to fight Mike Tyson at Madison Square Garden.
Mac: We got him to give you a three-round exhibition match.
Roz: Aw, this is the loveliest, sweetest, most thoughtful....(kisses Mac's cheek) I'll rip his freaking head off.

Eddie: Well, I-I kinda put her on the wrong bus.
Harry: You sent Mrs. Turley to death row?

New York does not have the death penalty, a fact that was pointed out in numerous previous episodes.

Eddie: Sign this.
Harry: What is it?
Eddie: It's a stay of execution.

In addition to the previously-mentioned goof about New York not having the death penalty, arraignment court judges cannot issue stays of execution.

Mac: (after tearing up resignation papers) Look out, ol' Macky's back!

The last line of the classic song "Mack the Knife." Bobby Darin's version in 1959 won the Grammy for Record of the Year.

Dan: (in whining voice) "I miss Mac, I miss Mac, I miss Mac." Hey, ob-la-di, ob-la-da, babe, life goes on.

"Ob-La-Di, Ob-La-Da" is a 1968 song by the Beatles. The chorus says, "Ob-la-di, ob-la-da, life goes on, bra, la-la how the life goes on."

Mac: Come on, Maurice, let's break open a bottle of that '29 Rothschild.
Dan: '29 Rothschild? That's worth about 950 bucks a bottle!

Chateau Lafite Rothschild is a real wine and real vintage year.
