Face It, You're Gorgeous - S9-E6
Continuity mistake: When Antonio is showing Ian the prison layout on the table, he uses crayons. He starts with a purple crayon in his hand. He draws on the paper. When we see the drawing, it's red. The drawing changes again after that.
Continuity mistake: The wall that Liam is building around Kev's kid changes during cuts. The most notable change involves the mud between the joints.
Continuity mistake: Pepa is driving a red VW Golf IV series, while two episodes earlier a red III series was parked in the driveway.
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.
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.
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.
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."
