Bob only appeared on two other CBS Game Shows besides "TPiR"...
"Match Game" as a semi-regular panelist
"Family Feud" w/ Ray Combs: "TPiR" vs "Young and The Restless" in 1991 and again in 1993.
He also appeared as a panelist of John Davidson's version of "Hollywood Squares" back in 1987 w/ Dian and Janice, and that was the only non-CBS Game Show that Bob had appeared on.
