Continuity mistake: The three selects that Dennis shows Dee, the guy with the black tank top and sunglasses is all the way to the left. When the shot switches the guy is all the way on the right - this is the guy Dee says is "One big chin." (00:06:00)
Continuity mistake: When Dee is standing up she is smoking a cigarette with her right hand. When the shot comes back to her as she cuts Charlie's joke off, the cigarette has disappeared and the bottle of whiskey has left the table and is in her right hand. (00:01:15)
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.
Continuity mistake: The way Dennis holds the 3 pictures of men changes. When he's showing them, he holds them next to his chest with one hand. Then when Dee's talking about them, he's holding them out with both hands.
Mac and Dennis Buy a Timeshare - S9-E4
Continuity mistake: When Dee and Charlie find Frank stuck, his arms are in different places depending on the camera angle.
Continuity mistake: The plane that Dee gets onto has winglets and a dark blue/black stripe around it. When seen flying in the next shot, the plane has no winglets and a red stripe.
Continuity mistake: When the waitress sits down with Charlie, some of the things in front of him move around. For example, when he pours the wine, the pipe and pen kept switching which side they're on.
Continuity mistake: When the gang barges into Dee's apartment they leave the door wide open. When the shot goes to Charlie and Dennis the door is half-way closed, when the shot goes back out to all 4 of them asking "Which one?" the door is open all the way again. It goes back to the Charlie and Dennis shot with the door halfway closed one more time before the scene closes. (00:02:20 - 00:03:30)
