Before Season 1Edit
An 11 year old Earl told Billy that his father's new Mustang was faster than Billy's car, and Billy challenged him to a drag race. Earl lost as he did not know how to get the car out of first gear, and he had to give the car up to Billy ("Dad's Car").
Earl went back to see Billy to buy the Mustang. However, Billy said the only way he would give up the car would be to race for it. Earl agreed, and with the help of Randy pushing he won the drag race, and won the car back.
