Pawn Stars star Chumlee was born Austin Russell; he got the nickname in elementary school. His friends named him after the sidekick of cartoon character Tennessee Tuxedo, Chumley the walrus.
Chumlee was a boyhood friend to Corey Harrison and having been around the shop since he was just a little kid, he's like another son to Rick Harrison.
Pawn Stars' 6th season is supposed to start before the end of the year, but until then if you need more of Chumlee and the Harrisons, Pawn Stars: Volume 5 was just released! It contains the very best episodes from seasons 3 and 4 (a total of 16 episodes), though no DVD extras.
