Well, obviously they just had to poke an eyehole or two in the box. "Hey, it worked, didn't it?"

He pulled the poor unconscious security guard out from behind the door, where he'd been propped. Then put him in the corner, used some plastic ties lying around to strap the guy's wrists and ankles, and a roll of duct tape in one drawer that, guess what, they were gonna use on this guy's mouth.

Then he put the box over the guard.

Perfect.

"Okay. We about done here?"
