To me, this moment represents the transition from growing up to entering the real world as this episode aired just weeks after I received my B.S. from UMBC, where I would watch some episode of Bob's final seasons between classes like so many other college students did at the time.
It was also the very last episode to be billed as "A Mark Goodson Television Production" (not including the Season 44 Decades Week cameos that had George announce it over the Freemantle Media logo), even though the production company had officially had been Freemantle since 2002, when Feud dropped the Goodson credit. This represented a 60+ year span on TV where the recognition of the greatest creator of game shows would come to an end, starting with Winner Take All in 1946 with his partner Bill Todman. Of course on Pluto, we'll soon see the switch from Goodson-Todman Productions to just Mark Goodson Productions.
Still, we have also received an encore from Bob twice in Drew's era, most recently for his 90th birthday in December 2013. Here's hoping Bob will be back one last time for his 100th, even if its just a letter like what Mr. Goodson did.
