My Name Is Earl
Karma affects people's personalityCompare Earl's personality during the pilot, he's selfish and greedy and is only doing good things because he thinks he will be rewarded, but by the end he does the good things because he's become a good person. And look at Randy, at first he's a bit slow, very crass and ill mannered. By the end, he's basically become a dimwitted, gentle giant.
Earl Jr really is Darnell's sonThe simplest excuse is that Darnell's toothbrush was new, and had not been used yet.
Earl Jr is EARL'S sonBut do the genetics work?
Earl died after being hit by the carEarl is in purgatory — a rather kind purgatory which, seamlessly simulating his real life, allows him to literally atone for every sin he's ever committed. This would explain why the hundred thousand dollars with which he funds his list projects (and pays rent, and buys food for two, and so forth) never seems to decrease. In this theory, there is a tenuous possibility that Catalina is some kind of angel.
The cop from "Cost Dad the Election" was working against Earl's dad and voted for the rich golfing guySeems odd that he'd send in a tape of Earl getting arrested for disorderly conduct twice for no stated reason other then to get the people of Camden to vote for the golf guy making the airplanes go over the community part the main cast and Earl's parents live in, doesn't it?.
At the end of "Bad Karma" Randy goes insaneHis line at the end, "It's my show now" wasn't him breaking the fourth wall, It's him not recognizing fact from fiction anymore as one of the people he loved just died horribly and he can't handle life anymore.
Earl is narrating from beyond the graveThis is similar to the first WMG on this page, but different enough that I'll give it its own heading. Earl didn't die in his initial accident, but has died by the time he narrates the show. The giveaway is in the first season episode "Boogeyman." Earl theorizes that, after death, people can watch their lives like a TV show. Earl and Alby (the kid Earl's helping out this episode) then greet their future selves. When Alby does it, he faces the camera and says "Hi, Earl." But when it's Earl's turn, he looks off to one side. The implication is that we're seeing this from the dead Earl's perspective.
The DNA test was taintedThink about it. Earl alerted Little Chubby that he had his DNA, and the results were delivered by Catalina. The Chubby's also have ties to nearly every business in Camden Country. It is VERY likely that he altered the results.
