Cop Out Easter Egg - They're a Couple of What?!?!

At the start of the movie when Tracy Morgan "interrogates" a criminal, Bruce Willis and a handful of other cops are watching. After he gets the info, Bruce comes in to finish. When they exit the room, the other cops laugh and one of them says "what a couple of dicks." The thing is, "A Couple of Dicks" was a working title for "Cop Out."
