Visible crew/equipment: When Frank is running back to Dee's car after speaking with Barbara and Ari, the boom mic can be seen entering the shot towards the bottom right corner of the frame. (00:12:45)
Continuity mistake: In the scene in the bar, when the lights go out, when they come back on, Dee's handbag is first seen on the floor in front of her. Then, in another shot, the bag is shown behind her. (00:15:03)
Dee Reynolds: Shaping America's Youth - S6-E9
Continuity mistake: In the final scene, in the principal's office, an orange magically appears on the desk in the middle of the scene. (00:20:08)
Continuity mistake: When Dennis and Maureen argue after he gets home from the strip club with Mac, Mac is shown standing in the kitchen carrying a liquor bottle in a paper bag.

(00:07:30)
The Gang Goes Bowling - S16-E7
Continuity mistake: The score for the boys doesn't match what we see. For example, Mac's first roll was a 7, but the score shows 8. And Dennis gets a strike, but the score shows spare. Later, when the girls trick the boys into performing badly, none of that is reflected in the scores. At some point after the 6th frame, Mac and Charlie roll gutter balls multiple times, and each on the first roll at least once, none of which is in the scores.
Revealing mistake: As Mac says "I'm very worried about these guys" and exits the bar, there's a shot right through the door and it's not the bar inside at all, just a wall with some pictures on it, much closer to the door than it should be.
The Gang Solves Global Warming - S14-E10
Factual error: When Charlie and Dee go to get ice, they go to a "liquor" store, down the road. In Pennsylvania, all liquor stores are state run, called "Fine Wine and Spirits", and only sell liquor and wine. In this scene, ads for liquor, beer, and wine are all on the outside of the business. Liquor stores in PA do not sell beer.
Gun Fever Too: Still Hot - S9-E2
Continuity mistake: When Mac and Charlie are outside the school taking kids' cell phones, the principal comes out. We see Charlie holding 3 phones and his gun. When Mac holds up his sword saying he's going to take the principal out, Charlie points his gun at Mac and is no longer holding any phones and the principal has them. Then Charlie is seen holding 1 phone and handing it to the principal, who is holding 2 of them.
Mac and Charlie: White Trash - S6-E5
Continuity mistake: When trying to get into the club pool, Mac takes two beers from the 6-pack that are from the same side, so that the remaining beers are in a 3 x 1 configuration. Later, you see on the table and when they're walking away, the missing beers came from the front so the remaining beers are in a 2 x 2 configuration.
The D.E.N.N.I.S. System - S5-E10
Continuity mistake: When Dennis is playing the voicemail from Caleigh, the way he holds the phone changes between shots.
Dennis Looks Like a Registered Sex Offender - S3-E11

Continuity mistake: When Frank pulls his weed out of the melon, he unrolls the bag. But in the next shot, it's rolled back up, and he's unrolling it again.
The Gang Solves Global Warming - S14-E10
Continuity mistake: When Charlie and Dee get out of the ride-share, she's holding her purse in her right hand. In the next shot, it's in her left hand.

Continuity mistake: When Dennis tells Mac to take a size pill, the bottle has the cap on. But in the next shot, the cap is off and in Dennis' hand.
Charlie and Dee Find Love - S8-E4
Character mistake: Near the end, when Charlie is leaving to be with the Waitress, Ruby says she wasn't using him "like Charlie was." She's talking about her brother and meant to say "Trevor."
A Very Sunny Christmas - S6-E13
Continuity mistake: When Mac and Charlie are still on Ricky's porch after he's closed the door, Charlie's hands are empty. But in the wide shot when they're leaving, Charlie is now holding the robot, even though it's meant to be a continuous shot because there's no break in their conversation.
Continuity mistake: When the McPoyles are telling their version of the night, Charlie grabs the guy in the grey mask and his hood comes off his head. But then it's back on.
