Continuity mistake: When Earl is in the Crab Shack discussing the punishing of the children, there is an empty tray on the counter in front of Crab Man, but when the shot changes, Crab Man is holding the tray with a bottle of beer on it. The shot changes back to Crab Man holding the empty tray, then changes back to him holding the tray with the bottle on it. (00:01:50)
Continuity mistake: Season 4, Episode 19, "My Name is Alias": While Darnell's farther has his back to Earl, Earl tries to jump him; Darnell's father hits Earl, and Earl falls to the floor. When Earl gets up, take notice that Earl has a cut on his lower lip; the cut goes from a vague light red to a dark red in several quick shots.
Continuity mistake: Near the beginning, when Joy sees the IQ game, the two poles are close together and there is nothing directly beside it. But when she gets close and the camera changes angles the poles are now separated and a small gold toy is sitting beside it. Then when she leans down next to it the poles are still separated, but the toy is gone. (00:00:40)
Audio problem: In the shot where Randy throws the glass of beer at the wall behind him in the Crab Shack, his mother's mouth is not synced with the audio that she is speaking: the audio was continued from another shot, and in this one, she is saying different words. (00:12:00)
Continuity mistake: Episode 10 of Season 4 ("Earl and Joy's Anniversary") has Earl yelling "Fire!" from inside the Crabshack's restroom. As he does, a woman with dark brown hair and wearing a blue plaid shirt gets up from her table to evacuate the restaurant. A long shot outside the restroom of Earl yelling "Fire!" has the same woman getting up and leaving again.
Continuity mistake: In S1E9 Randy asks Earl what animal he'd want to be. Earl says he'd rather be a dog than a cat because he is allergic to cats. However, here Earl is shown around cats with no allergic reaction. Instead, Randy is the one who has allergies.
Continuity mistake: Whenever Earl, Joy and Randy go to visit Jasper in the flashback, his Russian bride is in the background. She shouldn't be around at this time as earlier in the show Jasper is barely introducing the gang to his Russian bride years after the flashback occurs (S1E12).
