[6] Chumlee is often portrayed on the show as the comic foil,[7] but he often appraises items in his areas of expertise, including pinball machines, sports memorabilia, sneakers, toys, and video games.

When he was about 12 years old, he was given the nickname "Chumlee" due to his large face and chin, which prompted the father of one of his friends to remark that he looked like Chumley, the walrus from the animated TV series Tennessee Tuxedo.

[16][17] In the series, he is depicted as the comic foil, often made the butt of the others' jokes for his perceived lack of intelligence and his incompetence,[18] for which he has been referred to as a "village idiot".

[21] Chumlee appeared as himself, alongside Rick and Corey Harrison, in the episode "iLost My Head in Vegas", on the American TV series iCarly.

[3] As of 2013[update], he owned a collection of cars which included a Rolls-Royce Phantom, Maserati GranTurismo, Cadillac Escalade, Range Rover, and a 1964 Impala SS.

[22] By September 2013, Chumlee had altered his lifestyle habits and lost 75 lb (34 kg) in a year by exercising at a gym six days a week and improving his diet, including drinking more juice, eating more vegetables and abstaining from red meat, a change that was inspired by his father's death at age 54 from pancreatic cancer, two weeks before Pawn Stars debuted.
