I was watching Man with a Plan and they referenced the Beverly Hillbillies and Granny, they called her 'Granny Clampett'. That made me chuckle since her name was Daisy Moses, or Granny Moses. She was Jed's mother in law. As a fan of classic tv I just think its funny how people make that kind of mistake. I know its not uncommon but its just funny to me. It probably steams from the fact that the mean family name is the one most associate with the show. I thought it might be fun to lists the character with last names most people tend to get wrong.

I can think of three off the bat
Granny Moses (the Beverly Hillbillies)
Grandpa Dracula (The Munsters)
Fester Frump (the Addams Family, tv show not the movies)
