Season 5, Episode 21: Lady Bouvier’s Lover
When Homer’s father Abe starts feeling lonely and depressed, Marge decides to set him up with her mother, Jacqueline. To impress her on their date, Abe grabs some forks and some potatoes to recreate Chaplin’s famous dinner roll dance scene from The Gold Rush.
Jacqueline gets a kick out of this, until some lawyers find out what’s been going on:
Lawyer: “Sir, I represent the estate of Charles Chaplin. I have a court order demanding an immediate halt to this unauthorized imitation.”
