Visible crew/equipment: After Fiona is hooking up with a guy from Tinder, as she is putting her clothes on and the camera is on the guy, you can see the guy recording in the mirror. (00:06:57)
Fuck Paying It Forward - S8-E4
Continuity mistake: Every time the camera comes back to Ian sitting down, the pill bottle and blue cup in front of him change position. (00:07:45 - 00:09:10)
Weirdo Gallagher Vortex - S9-E3
Continuity mistake: In the recap, Carl says "documentation community service", whereas in the episode before he says "documented community service". (00:00:20)
Crazy Love - S5-E6
Continuity mistake: Liam is carrying Frank's shoe in the scene after running away, but he does not find the shoe until he leaves the jockey in a later scene. (00:22:32 - 00:25:31)
Continuity mistake: Pepa is driving a red VW Golf IV series, while two episodes earlier a red III series was parked in the driveway.
Two at a Biker Bar, One in the Lake - S11-E7
Visible crew/equipment: Frank is confused as he's at a foreign bar. He backs up against a glass window. A few crew members are visible reflected.
Continuity mistake: Kev hands a beer with lots of foam at the top to a customer at the alibi, then the shot cuts to the beer having no foam, then back to the beer having foam again.
Continuity mistake: When he is handcuffed, Mickey mentioned his dad dumping them on Family Services for a year. However, in the third season Lip said Mandy had "miraculously" never been in the system.
Continuity mistake: A call comes through the police dispatch radio of a kid stealing from a liquor store and the address of the store is broadcasted as "44100 Western Ave", but when Carl and the lady cop enter the liquor store from the outside, the address above the store reads "2420."
Visible crew/equipment: Carl is walking along the reporters trying to get their attention. At the bottom of the screen is the shadow of the camera filming the shot. It moves as the scene moves. At one point there is even a boom mic shadow on the right. While this may be a member of the news crew, it's likely the boom mic for the show as the reporter has a mic of her own and the shadow follows Carl.
I'll Light a Candle for You Every Day - S2-E3
Continuity mistake: In season 1, when Ian is looking for Mickey, Mandy mentions that Mickey went to take their mum out of jail. After, it is mentioned 2-3 times that their mum is dead. Mandy also specifies to Lip in season 2 that she's been dead since she was a baby.
May I Trim Your Hedges? - S3-E3
Continuity mistake: Kevin divorces his first wife in Season 3, Episode 3. But in Season 10, Episode 12, he tells Veronica that he will have to find her first to get a divorce before he can marry V.
Character mistake: When Fiona and Ford are lying on the mattress looking up at the compass on the ceiling, the compass is improperly painted. With west on the left, north would be at the top, not the bottom as depicted.
Character mistake: Iain and Mickey tell paramedics about an old lady needing immediate help in her apartment on the "5th floor" just before stealing their ambulance as the paramedics storm into the building. However, the apartment building has lots of units on every floor and no unit # was given in this fairly large building. Medics would have trouble finding her had this been a real call.
Factual error: Karen says she doesn't want to divorce Jody because he'll take half her life insurance payout in the divorce, but life insurance (as well as other inheritances) are not considered marital property and don't usually get divided in a divorce.
Deliberate mistake: When Dominique is creating a Tinder profile for Fiona (an app Fiona admits she doesn't use), she manages to use Fiona's phone to take a picture of her, create a profile, and quickly get three matches, all within a span of 25 seconds. Downloading the app itself would take longer than 25 seconds, much less agreeing to its terms of service, and verifying the email or phone number associated with the account. (00:45:15 - 00:45:39)
