Continuity mistake: Bartlett is in the executive office in the residence watching four TVs at once. He hears a line in the black and white movie, a second later he rewinds it to hear the line again - he rewinds way too much and for too long, but once he stops the tape, it plays the line he wanted to hear again right away. He went too far back (for visual effect) than what in reality it would have taken.
Continuity mistake: Toby, Sam, and Amy are sitting at a table talking - Amy's eyeglasses are on the table in front of her - when Toby asks Charlie what's on the TV, the shot shows her glasses have rotated 180 degrees and her arms have noticeably changed position.
Continuity mistake: Toby and Leo are in Leo's office talking about the friendly fire incident - Leo's glasses are sitting on his desk in front of him. He then picks them up and moves them to the far left. A couple of shots later, he picks them up from the right and puts them on.
Continuity mistake: While Sam and Donna are listening to a TV report that Sam may be heading for Congress, the woman behind him has a phone receiver to her ear, with both hands on the phone. The shot changes and suddenly her right arm is down by her side, but in the next shot it is back in the first position.
Continuity mistake: When the guys arrive outside Donna's building, Josh wears a tux and a long black coat with a white scarf. After Josh says, "The buzzer's not working", a few quick camera cuts occur, and as he says "Nah, I know women-" and turns, the scarf is missing. It is back as the cameras cut again and he says, "I know what they like."
Continuity mistake: Near the beginning of the show, Josh is talking about baseball while looking at some stapled political papers - the top one is folded back over the second one. As Donna asks "what is it?", the first page is falling free and Josh is only holding the second one, but he had no time to adjust them.
Continuity mistake: Bruno and C.J. sit down in a meeting and are talking about women voters. When the shot is on Bruno, we can see C.J. is holding a black folder that is partially open. When the shot goes to her, though, she has her hands on the folder, which is opened on the table.
Continuity mistake: Newly hired Assistant White House Counsel Joe Quincy is looking over his new "office". He's told it is the office traditionally given to newly hired lawyers, and is known as the "Steampipe Trunk Distribution Venue". In prior episodes, Ainsley Hayes, the previous Assistant White House Counsel, was also given this office, but this space is significantly altered in size from the earlier appearances. Essentially, the length of the space has been cut in half and the intervening wall with door is gone. Yet the room is not newly remodeled. It's a basement space with old pipes and walls, etc. The makers simply shrank the set without explanation.
Continuity mistake: Early in the show, Toby, Sam, and C.J. are at a conference table, talking about a concession speech. C.J. is holding a mug and scratching her hand, but as she turns and says "ooh, Mr. Lyman", her mug is suddenly sitting on the table. In the next shot, as she is talking to Josh, her hand is around the mug. None of these changes happen in natural time.
Continuity mistake: In season one, CJ's office was right next to Josh's office, but from season two on, it was at the opposite end of a long walkway that runs between several glass cubicles (one of which Donna uses). The later location for CJ was the press room for season one. The differences are not furniture, etc, but wall and door locations have been revised. This season four episode features a flashback where Donna visits the White House prior to Bartlet's inauguration, and she is led to her future cubicle. In this scene, we see the floorplan is not the earlier version, but the newer version. While the between-season changes can be excused as 'remodeling' that took place off-screen, this episode's arrangement can't make sense.
Continuity mistake: In the closing minute, when C.J. Is trying to stand the egg on its end, the camera pans to the clock for DC, and it reads 12:00. But as she sits at the table, her watch reads 7:15. Then, in the next camera shot, zooming in onto the egg, you can see that C.J.'s watch reads 7:25.
Continuity mistake: When Donna and Amy are talking about 'getting' Josh, there's a cut from Amy rearranging the beer bottles on the table to a close-up of Donna standing a distance behind her. When this happens, a beer bottle is suddenly in Amy's hand with her holding it to her mouth.
