The Beverly Hillbillies S02 E23 The Critter Doctor

"Y'all come back now, ya hear?"

Ellie has Dr. Martin of the zoo come over to treat her dog Duke who is sick. But Granny mistakes a bug repellent salesman Jim Gardner, who ends up falling for Ellie, for the veterinarian. Granny thinks he is no "Critter Doctor" but actually a "Bug Doctor" who is there to sell "bug vittles". Granny is taken with Dr. Martin, after finally meeting him.
