Ed Big Daddy Roth,
Mr. Gaines missed the boat on this genius idea - I could see the Rat Fink being in Spy Vs. Spy Vs. Spy (w/the Boss Hoss!)
Bill Gaines was DEFINITELY familiar with BDR's creations. I'm guessing dementia was setting in with the old man and he probably needed photo visuals of Rat Fink and other related Roth crazy stuff to make the association. And I bet that would have also lead to dollar signs dancing in Gaine's eyes, too.
