Here's the first part of a holiday crossover between The Beverly Hillbillies and Petticoat Junction from 1968, which would be season 7 of Hillbillies and season 6 of Junction. Seems Granny (Irene Ryan) has been in a long-distance relationship with Hooterville's multi-tasking ace Sam Drucker (Frank Cady), and two of the Bradley sisters are swooning over Jethro (Max Baer, Jr.).
Take note of some product placement at the start, although the Kellogg's logo was cloaked from a box of Corn Flakes as Jethro's eating breakfast. I think that's because Kellogg's was no longer sponsoring Hillbillies.
If I didn't know any better, I'd think that the chimp would resurface on ABC's Lancelot Link 2 years later, since Frank Inn trained the simian cast on that series.
No rating. Have little memory of seeing this episode or the next one, which we'll have up soon.
