At Homicide, Bunk sits at his desk, a visible cloud of dread hanging over him. He shoots a hateful glance over at McNulty -- the latter gabbing away on the phone, apparently to Freamon, about the newly constructed surveillance units -- and, his loins sufficiently girded for the humiliation to come, gets up and walks over to McNulty, piece of paper in hand. Bunk sets the paper down in front of McNulty and then holds out a pen. McNulty, summoning his inner dick, turns his full and undivided attention to the phone call with Freamon, leaving Bunk hanging. After hanging up, McNulty glances at the paper, then at Bunk. "Just sign the motherfucker and shut the fuck up," Bunk snarls. I'm guessing that Bunk is finally taking advantage of all those excess police resources McNulty has at his disposal. That guess is confirmed by McNulty, who smirks throughout the signing process and keeps smirking even after handing the paper back to Bunk. To his credit, Bunk does not conclude their transaction by jamming the pen into McNulty's jugular. Good thing, too, because Kima's shown up to accompany McNulty on his road trip to the FBI, and it would have been awkward to have McNulty gurgling blood for the entire drive down the Baltimore-Washington Parkway.
