When Lois presses a button on the remote control in Garret Grady's office, a shelf extends and a synthetic voice says, "Holodeck active." This is a reference to the fact that Dwight Schultz, who played Garret Grady, previously played Lt. Reginald Barclay on Star Trek: The Next Generation (1987) whose activities frequently involved the holodeck.
At 15 minutes into the episode, when Jimmy gives Clark a fax, a boom microphone is seen at the top right dropping into frame.
