|First Appearance||Hamhocks and Armlocks|
Earl is a large and aggressive truck driver. He enjoys arm-wrestling with patrons of the Truck Stop (such as Clem), just as much as he enjoys country music. He only appeared in the episode Hamhocks and Armlocks, where he served as the episode's main antagonist.
Because of his sheer size, his face is never shown throughout his appearance (a theme the animator, Craig McCracken, has been known to employ).
After Earl challenged Dexter's dad to an arm-wrestling match for switching his favorite record in the jukebox, Dexter built his father a cybernetic arm, which allowed him to beat Earl in the match and send him flying through the Diner's wall.
