S3·E23 Drysdale's Dog Days

Granny demands to see her money in cash, and Drysdale tries to talk her out of it. He fails and upsets the Clampetts by accidentally throwing magazines at them, which were really aimed at his wife and her dog. He tries to make things better by showing Granny what a million dollars looks like to turn her off from the idea, but ends up throwing more stuff at her.
