This episode is not one of the greatest of the series but it is a good solid episode. Earl's finding of the badge is a good reference to karma. His flashback to the abuses with the badge are pretty good and how each character abuses the privileges is humorous. It also introduces Clint Howard's Rodney as a true scumbag.
The policeman's family of sister and police captain, as well as the scene of him as a baby involved in an arrest, was pretty good and the girl's hairstyles are a laugh all on their own. The policeman, played well, at the rest stop having to be a janitor was also a good chuckle.
Best of all probably was the ending. With Earl finding out why he should not tell everyone (especially cops) about his list and Rodney getting his karma payback. Definitely an episode worth watching but on a show this good, even this good episode has trouble measuring up in a few ways. Maybe that is the problem with a great show, that episodes that would be outstanding on other series are just average.
