Continuity mistake: At the beginning of the episode, Earl says that costing his Dad the election is 4 on his list, however, on the list that they show during the title sequence of each episode, "Cost Dad the Election" is 65. (00:01:10)
Continuity mistake: At the end when Stuart decided to let Earl go he pulls the list out of his pocket, and gives it back to Earl, and it is all crumpled up, but a second later when we see Earl holding the note it is neatly folded.
Number One - S1-E24
Continuity mistake: When Randy is scratching off the joke lottery ticket, the amount of scratched-off material left on the ticket changes between the three close-ups. One shot shows that the ticket was rubbed and not scratched (the area revealed has a haze to it).
Continuity mistake: In this episode, during the narration, Earl says Catalina spent 4 days on a raft to get to the USA. In Y2K, 1:19, they showed Catalina's trip to the US and there was no raft involved. It was entirely an overland trip.
Barn Burner - S1-E11
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: Just after Earl realises the Mustang he lost was supposed to be his, Joy sits down with a pitcher of some cocktail. It moves around between shots, alternating between being in front of Randy and being in front of Joy.
Number One - S1-E24
Continuity mistake: Just after Earl sells the car and he's arguing with Randy, you can see a red fence in the background behind Randy. The shot cuts and then it's behind earl and it cuts back and it's behind Randy again. (00:19:00)
Continuity mistake: At the start of the episode, when the cop runs over to Earl, he drops his gun. When it shows the gun again, it's moved about three feet on the ground.
Continuity mistake: 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.
Visible crew/equipment: In the scene in Y2K when you see Donny Jones jumping around in front of the TV screens, as the camera slowly moves in past the TVs, you can see the camera man and the camera actually shown on the TV.
Reading Is a Fundamental Case - S4-E12
Continuity mistake: In episode 11, Earl's list item was to give back the blue door, but in this episode he still has the door.
Suggested correction: That's because the episode was aired out of order. This episode was the 9th one produced (production code 4ALJ09), but aired in between the 12th and 13th episodes produced.
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)
Witch Lady - S4-E21
Continuity mistake: In the scene where Randy is rolled down the basement steps in a bag, there is no foot protruding from the bag; once Randy reaches the bottom, the foot is sticking out.
Larceny Of A Kitty Cat - S2-E4
Continuity mistake: While Randy is hugging Judy, the cat is watching them. After she agrees to give up the cat, the cat has both its ears straight up. The next shot from behind, the cat's head is tilted to the left and his left ear is bent down.
Earl and Joy's Anniversary - S4-E10
Continuity mistake: Earl yells "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.
Other mistake: When Earl meets with Kimmi in her room, she's supposed to watch "You've Got Mail" - her TV, however, is switched off.
Character mistake: While filming the cheerleader performance, Jasper refers to his inability of using computers ("We're gonna put this on YouTube as soon as one of us figures out how to use a computer!"). Earlier in the series, however, Jasper ordered himself a Russian wife online, so this statement is definitely off-character.
Continuity mistake: When Earl accidentally kicks Joy with the ball, it hits her upper forehead, nowhere close to her nose which is broken afterwards.
