S01E21 The Bounty Hunter
In flashback, we go back six years in time. Earl was going out with Jesse, but one morning, he woke up to find himself married to pregnant Joy. When Jesse tried to understand why she had been ditched, Joy punched her in the face, and she lost two teeth. After training for six years, Jesse is back in town, and she is after Joy. Earl tries to calm her down, but without success, so he has to hide Joy in a caravan. Joy then reveals how they got married, and strikes out number 45 - "Ditched Jesse to marry Joy" - for him, saying it wasn't his fault.
