The connection between Petticoat Junction, Green Acres and Beverly Hillbillies

I watched these shows coming up, but I didn't know there was any connection. My mother was telling me about it today. Hooterville is the name of the town featured in both Petticoat Junction and Green Acres. Sam Drucker runs the store in Hooterville. He also once dated Granny from Beverly Hillbillies. In one of the episodes on Beverly Hillbillies, Jethro visited Hooterville and ran into some characters from Petticoat Junction. There's a few crossover episodes.
