Beverly Hillbillies

The Beverly Hillbillies were planned to be reported on in a "new comic for girls", which would be edited by Lady Penelope Creighton-Ward. (PROSE: Time Barrier Busted)

Behind the scenes
The "Beverly Hillbillies" were the titular characters in The Beverly Hillbillies, which had a UK-exclusive comic spinoff in the mid-1960s. The family consisted of Jed Clampett, his daughter Elly May Clampett, her maternal grandmother "Granny" Moses, Elly's cousin Jethro Bodine, and Jethro's mother Pearl Bodine.

In TV Century 21 and its spin-off Lady Penelope, the Clampetts are treated as real people who Lady Penelope gets acquainted with. However, Time Barrier Busted is the only story with any significant Doctor Who universe connections to reference them.
