The ambulance pulls in and Carter makes like Geddy Lee rushing over to it. "Dr." Dave Malucci is close on his heels, and confirms that Carter is "with [him] on this one." Doris gives them the bullet: it's a fifty-year-old man found in a park, in full arrest. Dr. Dave comments, "That's one well-fed bum." I guess he's supposed to be fat, but it's hard to tell because of the angle from which they're shooting him, and because he's completely covered -- except his feet -- by one of those red insulated blankets. Lisa wonders how they managed to get ParkBum into the rig, and Doris replies, "Paid a bunch of his buddies five bucks." Heh. Lisa and Dr. Dave look dismayed, but Carter claps his hands and leaps into the rig, anxious to start the healing. And showboating. They go hand in hand, really.

ParkBum's bed rolls into the ER as Doris continues: "Large lac to the occipital scalp; not sure if he was rolled or fell out of his tree." Dr. Dave wants to know what he was doing in a tree, and Lisa suggests, "Maybe he lived in it." Yeah! Maybe it was a political act! Aw, right here in Chicago -- their very own ParkBum Butterfly Hill. Dr. Dave does compressions on ParkBum's chest (they've folded down the top of his blanket) as Carter notes that ParkBum's in asystole. He asks Doris why they didn't intubate ParkBum, and she replies, "His neck is as thick as a power pole! We couldn't find the cords." Carter comments that it was forty degrees out last night, and that ParkBum is hypothermic, but they still might get him back. Dr. Dave mutters, "Oh, yeah? With what? A blowtorch?" No, Carter's thinking of active core re-warming.
