Character mistake: During the radio show, the radio host gives the radio station's phone number as 555-4455, Alf then softly repeats the number back before he gets to the phone. He then picks up the headset and dials a number, but the numbers he presses on the phone don't match up to the number given by the radio station. (00:04:10)
Character mistake: When Ginnifer Goodwin leaves the supermarket to go the parking garage, the green sign says 1 hour parking Customer's Only. It should say Customers Only, without the apostrophe.

Character mistake: In Bill's office, after Tim talks about the acoustics in the building, Bill calls Tim "Bill." (00:15:51)
Character mistake: At the Roadhouse Cooper states that the second victim (Maddy) was found dead two days ago. It has been less than 24 hours since the body was found: he likely means she was murdered two days ago.

Stop Me Before I Hug Again - S1-E13
Character mistake: In Brian's "Laws I Have Broken Since Joining FBI" list, item #30 misspells the word "recorded" - "30) Recoreded NFL Game Without Consent." He'd only have that knowledge if he was using NZT, and if he was, he wouldn't make a mistake like that.

Clyde Bruckman's Final Repose - S3-E4

Catch A Falling Star - May 21, 1979 - S2-E10
Character mistake: In the preview for this episode, Charlie has trouble getting his countdown straight. He shouts that Sam is on in 50 seconds, then 47, then 48. In the episode itself, the mistake is corrected with a rather obvious overdub, changing the final number to 43. (00:02:05)

Old Wounds - S1-E1
Character mistake: After Mercer's speech to the entire crew he dismisses everyone except for the senior staff but everyone, including the senior staff, starts walking away as if they were dismissed as well.
Suggested correction: They were walking away, but not as if they were dismissed. The group of senior officers and Mercer are in a completely different part of the room (or possible an entirely different room). Notice the doorway where Mercer is standing. At the beginning, he's in the doorway and it has a white boarder and a 2nd set of doors. Then he's standing in front of a doorway with a blue boarder and no 2nd set of doors.
Character mistake: The Enterprise is targeted by projectiles from the planet. Spock identifies them as "plasma torpedoes", and Captain Pike reacts with surprise; "Plasma torpedoes? That's 21st century tech" and from that they all establish that the civilization they contacted is not yet capable of warp drive. Plasma torpedoes are the main weaponry of the Romulans centuries later, and Earth itself did acquire warp drive in the 21st century, so this claim and deduction don't seem to add up. (00:22:15)
Character mistake: The sign in front of the tank Lt. Ladd is trapped in reads "ORDINANCE TESTING FIELD, DANGER.", but an ordinance is a type of decree or law. They probably meant 'ordnance', which is another word for artillery.
The Way of the Warrior (2) - S4-E2
Character mistake: During the Defiant's flight to save the Cardassian officials, Worf says something to the effect of, "I've never been aboard a Federation ship equipped with a cloak before".

Chapter 9: The Marshal - S2-E1
Character mistake: Cobb Vanth says that he's never seen anything but the dragon's head and had no idea about the size of the dragon...but at the beginning of the episode we could see the beast pass through town (conveniently right in the main road without damaging anything else) and its enormous lengthy body was perfectly noticeable. (00:31:20)
Character mistake: When Charlotte is going into Henry's dream for the first time, while she is talking, in the background, you see Henry move his head and open his eyes.
Remembrance - S1-E1
Character mistake: Picard and Data are playing poker at the beginning of the episode. Before the actual faces of the players are revealed, we are shown close-ups of their hands as they put down the chips for the bet. When Picard says his first line in the series it's "See", and it is literally true, because in the previous shot, Data put his 5 cards down on the table and face up. (00:00:50)
Character mistake: Raymond refers to his equipment as EMF (Electromagnetic Fields), except it is labelled as EMR (Electromagnetic Radiation).
