It's Earl's birthday and time for Earl to celebrate and reflect on his life. Randy throws him a party and gives him a half-priced cake. He reminds Earl about a previous time when he tortured Randy with "Jackass" style stunts. Earl's mother reminds her son how he once used her living room as a toilet. Earl reminds everyone it's time to focus on "good" Earl.
The bad memories continue to pour in, and Earl cringes about the "Bad Earl" days, like getting Darnell busted for selling brownies with no pot in them. In an effort to "make nice", he hands the Karaoke mic to a resentful friend, who sings a bad version of Pat Benatar's "Heartbreaker" entitled "Fern Breaker".
Joy reminds Earl of a painful memory: A pregnant Joy, disturbed that the trailer park's resident peeping tom is ignoring her, asks Earl to help her. The pervert is actually Earl, on an undercover mission to find a big screen television. Despite Joy's announcements each evening that she is having sex, the trailer park pervert continues to ignore her. Earl suggests that they "bring another girl in". He pays his friend Johnny to creep out the neighborhood.
Joy catches the Peeping Tom and the neighborhood women beat him up. One of them hits over the head, saying "That's for peeping me before I was done with Jenny Craig!" At his birthday, Earl confesses to Joy that he was only trying to make her feel better. She reminds him about all his terrible pregnant jokes when she was in a sensitive predicament: having another man's child.
Randy recounts some of his and Earl's bad one-night stands, including one with a woman, "Dee Dee", who leaves her prosthetic leg lying on Earl in bed. To "compensate" for the experience, he steals her wallet and beats her with the detached leg. As he drives off, the woman fires a shotgun at a freaked-out Earl.
At his birthday, Earl's dad gives an impassioned speech, but it's just another reflection of a bad memory. As a child, Earl dopes up his dad with his friend Eric's mom's pills (Melody Thomas Scott in a hilarious cameo), and his father becomes the laughing stock of a party. By embarrassing his wife, Earl's dad is confined to the couch for weeks — which is when his back problems begin.
Surrounded by bad memories, Earl's birthday celebration is a flat-out bust. Walking home from the bar, he comes face-to-face with a menacing Dee Dee, the one-legged woman with a chip on her shoulder. She chases Earl home to a big surprise party, Randy's idea. His dad wishes him a "Happy Birthday". Each family member picks an item and, as a gift, crosses it off Earl's list.
As Darnell presents him with a cake, Dee Dee, the one-legged lady, hammers on the door. He wishes her to go away and she finally leaves. The party begins and Earl finally gets drunk enough to wow the room with his "breaking".
