Wayne is one of the three Freesiders that were attacked by NCR soldiers in the quest G.I. Blues, along with his friends Roy and Farris.
Wayne is a scavenger in Freeside. He, Roy and Farris just cashed in some scrap metal and decided to go to the Atomic Wrangler to try their luck at the slots when an attack occurred between two parties and they were caught in the crossfire.
Putting the names of the three men together, you get "Roy Wayne Farris" - real name of WWE Legend The Honky Tonk Man, who wrestled with an Elvis impersonator gimmick and is also the cousin of Jerry "The King" Lawler.
