That is, characters that are often refered to on the show but are never actually heard from directly.
Officer Harraps(sp?) - Scary cop that is known to bust many of Tom's enemies.
Werner - A murderous drug dealer who looks like Rutger Hauer only shorter with blonde hair and a black mustache.
Roy Jr. Rhoda Jr. and Rhoyda - The spawn of Philly Boy Roy Zeigler and his wife Rhoda.
Roy Jr. in particular seems to hold an unhealthy influence over PBR and often gets his father into trouble with the law. He is 13(?) and yet he drinks and drives and engages in other adult activities.
