His childhood experiences in "The City of Brotherly Love" were the basis for the Scharpling & Wurster character Philly Boy Roy. Philly Boy Roy's voice and mannerisms are based on Tompkins as well. Tompkins is credited with winning the inaugural "Running of the Cheesesteaks" in 1988. Philly Boy Roy would later popularize the event in a "Scharpling & Wurster" sketch.
The PFT/PBR connection is absolutely false. I've always suspected that PBR is largely based on Mitch Rochon, the troubled cousin of Flag of Democracy bass player Dave Rochon.
