My name is Earl
In the show, Ethan Suplee's character, Randy, is portrayed as a bumbling idiot with sweet and usually kind intentions as he follows and accompanies his brother in his daily exploits. Randy is presented as a docile and predominantly innocent character. His appearance backs up the stereotype of overweight individuals being more jolly than people of smaller stature, due to his actions in the show. Randy's scruffy looks make him come across to the audience as more loveable and jovial, causing him to become a fan favourite.
Jaime Pressley's character, Joy, is shown to fit the stereotype of America's "Trailer-Trash". She lives in a run-down trailer park in a small, run-down trailer. Though her living conditions are sub-par, she still runs a family of four. Although she isn't portrayed as particularly dopey, Joy comes across as relatively uneducated with more "street-smarts" than anything else. This is present in her value for aesthetics as opposed to academia, caring more about her looks than most other things.
Eddie Steeples character from the show, Darnell "Crab Man" Turner is a very peculiar character. Due to his former alias, Harry Turner (former government agent), being put into the witness protection programme. Crab Man is represented as a simple man with a happy-go-lucky aura about himself. Often being the voice of reason, Crab Man's docile demeanour makes him the unlikely brains of the cast.
