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)

My Name Is Earl (2005)
1 audio problem in season 4 - chronological order
Starring: Jason Lee, Ethan Suplee, Jaime Pressly, Nadine Velazquez
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).
Police officer: It's police policy not to waste resources looking for a missing person in the first 24 hours because they usually show up on their own, and after 24 hours, if they're still missing, it usually means they're dead and we don't look for them that hard then either.
Trivia: At the end, Earl's father says that he talked to John Sheppard earlier that day. Earl's father is played by Beau Bridges who portrays General Hank Landry on Stargate SG-1. John Sheppard is the main character of Stargate: Atlantis, SG-1's sister show.





Answer: The premise of the show is he atones for mistakes he did in the past. Winning a car for Joy probably atones for something he did wrong regarding her in the past.
