Remeber during the Second Brady Bunch movie the attempted to make connections with Gilligan's Island. A man with a mustache refers to "my son Gilligan." Mrs. Brady refers to "my first husband, the Professor." The plot of the movie centers around a con-artist who inpersonates her first husband, named Roy Martin. The professor on Gilligan was indeed named Roy, but it was a Roy Hinkle, NOT a Roy Martin. How did this happen?

Maybe they were meant as inside jokes, that only the fans would get.

I'm going to have to watch that again, i never noticed.
