Quote from Michael Scott in Branch Wars
Michael Scott: This is perfect! Dwight K. Schrute: He looks like your twin. Michael Scott: This is a dummy, a la "Ferris Bueller's Day Off". We have tied a string to the wrist, which goes to the door. When somebody opens the door, the hand goes down, hits the remote, turns on the tape recorder, which is me snoring. Now, nobody knows whether I am here, or whether I am gone. Dwight K. Schrute: I will know. Michael Scott: But you will not tell anyone. Dwight K. Schrute: I won't need to because we'll be together playing hooky. Michael Scott: Yeah. Well, sometimes. Most of the time I will be with Ryan, or Darryl.
