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.
Familia Supra Gallegorious Omnia! - S6-E12
Continuity mistake: The baby has feces on its backside which the doctor talks to Deb about. It disappears during the scene and never reappears. No diaper was changed.
Be a Good Boy. Come for Grandma - S6-E8
Continuity mistake: The sign on the door "Carl's Crib" gets bumped and is off kilter near the beginning of the episode. When Carl's friend shows up, the sign rights itself.
Crazy Love - S5-E6
Revealing mistake: Ian is looking for a parking spot in Indiana. There is a shot looking at him and the speedometer of the car is visible. It is not moving despite Ian driving.
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)
