I was of the Sonny Fox era of Wonderama. I remember a cool guy in a business suit, who gave out an unending supply of toys and cool stuff at the slightest win of the slightest competition (how can I get on this show?!?!). At some point the goofy, wannabe-cool Bob McCallister replaced the smooth-as-Nutella Fox, who eventually became the VP of children's programming at NBC.
