And Then There Were 7 - S1-E11
Continuity mistake: When Quinn falls in the well, he falls through and subsequently destroys the well cover. At the end of the episode when the Secret Service boys show up, an undamaged cover is lying next to the well, which Kellerman uses to cover it up. (00:29:30 - 00:38:30)

Other mistake: At the start, it's nighttime when the unsub hides in the house of the soon-to-be victim who goes to sleep when her alarm clock reads 'Tue 11:06', and then we see the time morph to 'Tue 1:13' when the victim is sound asleep, before the unsub comes out of the closet to kill her. However, the time on the clock should actually read 'Wed 1:13'.
Super Grover

Plot hole: In this episode, the Duboises make such a big deal about Ariel being old enough to finally learn to drive. However, two episodes previously ("Things to Do in Phoenix When You're Dead") Ariel drove herself to school and Joe complimented her on her prowess.

Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.
Ronnie Bischof
Factual error: The Roswell, New Mexico sheriff forces Bones to examine the body because it was found in his jurisdiction. But later in the episode, we learn that the body was found 2 kilometers from the border of Mexico. Roswell is not even in a county on the border of New Mexico much less one that borders Mexico. In fact the closest border to Roswell between the US and Mexico would be in Texas - hours drive away. The Roswell sheriff would have no jurisdiction.
Myridon
Continuity mistake: Season 5, episode 5 "Van Nuys": When Silas is painting the wall green, some parts jump from being painted to unpainted between shots.
RoyT
Continuity mistake: In the scene where Karen is about to process the sample from the bathroom the vial is in her right hand and the swab in her left. In the next shot the vial is in her left hand and the swab in her right.

Continuity mistake: At the beginning of the episode, Earl says that costing his Dad the election is 4 on his list, however, on the list that they show during the title sequence of each episode, "Cost Dad the election" is 65. (00:01:10)
Captain Defenestrator

Continuity mistake: When they first bring the girl to the house with the storm and lay her on the bead the there candles next to her. First the tallest one blows out then the middle one blow out then the shot changes and the middle candle blows out again.

Factual error: When Rose is introduced to the entire team McGloin shakes her hand and says that he (respects or admires) anyone that has survived the POW school. She smiles, nods and walks away. McGloin then explains to the last remaining teammate that all NIOs attend the POW school and explains briefly what it is. First: It is the SERE school. Survival, Evasion, Resistance and Escape not really POW. Second: Not all, not even most, NIOs attend SERE school, just some.

You Are Here - S1-E7
Continuity mistake: Brenda's rape scene scar moves from directly above her left eye to directly above her right.

Episode One - S2-E1
Factual error: During this episode, Vincent is remanded to prison for suspected murder. At one scene he is seen working on the wing. Remand prisoners are not expected or allowed to carry out work duties in British Prisons.
