The Lame Duck Congress - S2-E6
Visible crew/equipment: At the end of the episode there is a camera visible in the oval office. After President Bartlet and Toby leave the office an attendant enters to turn off the lamps in the oval office. The scene widens as the lamps are turned off such that the audience can see the entire darkened room. The production equipment, a camera on tripod, and even a crewmember's leg are visible between the penultimate and final lamps being turned off. (00:41:50)
Continuity mistake: During the beginning before the opening credits, C.J. is briefing the press corps on the bus. In the outside shot of the bus, C.J. has her left arm resting on a rail, towards the door. When the shot changes to inside, C.J. has her right arm on a rail towards the driver. (00:01:15)
Chosen answer: A really annoying innate lack of sense. My friends and family say the same thing all the time, and I'm endlessly trying to correct them. I think people just don't know any better and (ironically) couldn't care less that they're speaking incorrectly.
