The One With Rachel's Date - S8-E5
Revealing mistake: In the scene in the coffee house, Phoebe is talking to Monica who is drinking a cup of coffee. Towards the end of the scene, the camera is on Phoebe who is smiling and laughing at Monica. In the right-hand corner is a side view of 'Monica'; however, it is not Courteney Cox in the scene but a completely different actress. [Widescreen version only, although the "wrong" nose is visible in the original]. (00:06:20)
Subway Wars - S6-E4
Revealing mistake: When Ted uses his laptop to get directions to the restaurant, Bing shows Los Angeles (where it's filmed) as their current location, instead of NY where the show is set. (00:02:15)
Punk Chick - S1-E22
Revealing mistake: While cuddling in the car Donna tells her boyfriend that she isn't wearing a bra when it is obvious that she is - at one stage when she leans toward him her sweater tightens across her back and the shoulder strap and clasp of her bra is outlined.
Episode Five - S1-E5
Revealing mistake: The mirror over Barnabas' mantel hangs flush against the wall. Yet when he shatters it, the candlestick he throws can be seen to go through the glass instead of bouncing back as it should have done. (00:43:45)
Revealing mistake: Jack Albertson's character is taking pictures of The Cartwrights and ranch hands. The video camera moves across the front of the prop camera as Albertson pushes and holds the button to take a picture. The shutter on the camera never opens and isn't open until he releases the button. In those days the shutter had to stay open an elongated time to enable the light to infiltrate the negative. People had to stay still during this time.
Revealing mistake: Before Jason Dean is shot outside the penthouse, Phoebe is waving her hands trying to convince him that the world is not real and you can already see blood on her fingers.
To Thine Old Self Be True - S7-E20
Revealing mistake: When Reagan drops her bag in the hallway when she is talking to Frasier, a lettuce rolls towards him. It didn't fall from her bag: if you look closely you can see it was tossed into the frame from just outside the camera view, obviously to ensure that it would land at Frasier's feet for the comic effect of him kicking it back to her.
Revealing mistake: When Georgia walks into Billy's office naked, a triangle-lamp will cover her "naked" breasts. Look closely, for at one point you can see the white, strapless bra.
Revealing mistake: In the scene where the king and his entourage are walking through the crowd, someone in the crowd (right side) is wearing a watch on his left hand while applauding.
Revealing mistake: When Leland Palmer is locked in the cell he starts screaming and runs headlong into one wall, then the other. The first wall wobbles noticeably on impact, indicating it is being shot on a set.
Revealing mistake: When Carrie bumps into Mr. Big and her purse falls, watch the people in the background carefully. Many of them are watching the couple talk and interact with each other. On a busy New York street nobody is going to pay attention to two people having a conversation. Apparently all these people were watching the shooting of the scene.
Revealing mistake: The phone message that Ryan leaves on Luke's voicemail is different to what he originally said, which is "I want to make sure you took care of it. Take care of it," but the message recorded is, "I'm just calling to make sure you took care of it. Take care of it." Also the background sounds from the club - the music, people talking, etc, are missing.

Revealing mistake: When Wanda traps Magneto in the force field thing, for one shot, Magneto is missing a sleeve on one arm, then it comes back a shot later.
Revealing mistake: Kevin McKidd's Scottish accent appears every now and then. For example in this episode, when he says that Marc Antony "negotiates with a whore and a dwarf at his side".
Mother and Child in the Bay - S2-E2
Revealing mistake: When Bones and Booth are driving in his SUV talking about Abraham in the Bible, you can see that Bones' side window is lowered almost all the way down, but her hair is perfectly still and not being blown around as it normally would be.
Revealing mistake: 3-2 "Walk Slowly": When Vincent brings her body back to the apartment and places her on the bed, the "dead" Catherine is visibly breathing. (00:03:30)
Suggested correction: Depending on the location settings on his laptop, they could be giving a false reading. My laptop shows I'm in Cardiff Wales while in fact I'm nowhere near.

The show was actually filmed on a film set in Los Angeles which is probably why the laptop says Los Angeles as the current location. This most probably slipped past the editing crew.
