Cook's Tour - S1-E4
Other mistake: When Johnny and Roy visit the woman they assisted in delivery, they go through the ER's double doors opposite receiving, as if heading upstairs to her room, and soon she even comments that the baby was brought up to her from the ER. Then, when the guys leave her room, Roy pushes open the door on the right, and we can see the ER's treatment 5 and the silver cabinets right up the hallway, so we know that Roy and John were actually in the room just off to the side of the nurses' station in the ER.
