Johnny Cash is Kevin's Idol, and believed to be the only singer that Grognak the Destroyer, Attorney at Law, Esquire, M.D knows. He is famous for singing a very emotional K-Pop song called Ring of Fire.

Grognak The Destroyer once started to cry whilst singing about that damned ring of fire.

Although not confirmed, Johnny Cash may be the only person that Jim Pickens looks up to, in fear and admiration.
