"Dr. Jekyll & Mr. Duck" is the sixtieth episode of DuckTales.
The episode opens in London, where Jack the Tripper (actually Professor Moody Doody) is seen running from police. He runs in Dr. Jekyll's mansion, where police stop pursuing believing he would never go there. He finds a notice on the door.
The scene cuts to Duckburg, where an auction is being held. A chest from London is put up for sale, and Uncle Scrooge buys it up, after a sort auction war with a "mysterious gentlemen in a funny hat". After it is opened up, Scrooge is in shock to find how "worthless" it is, judging on the contents (which were a cape, a hat, and a strange potion). Believing it to be cologne, Scrooge sprays himself with it, and immediately begins giving money away. The potion gets stolen by the same man who had wanted to buy it at the auction. Meanwhile, Scrooge's behavior deteriorates, and he begins calling himself "Uncle Moneybags".
Scrooge and the nephews go to London to find a cure. There they discover Dr. Jekyll's mansion.

- Scrooge says "Don't call me Shirley", a reference to Airplane.
- Shedlock Jones and Professor Moody Doody are parodies of Sherlock Holmes and Professor Moriarty respectably and Moody Doody’s alias Jack the Tripper is a parody of Jack the Ripper.
- Shedlock Jones notes the six hour time zone difference between London and Duckburg. This is contrary to the portrayal of Duckburg as being on the West Coast, as the time zone six hours before Duckburg would be Central Time. This is probably an error.
- The scene where Scrooge is at the auction is similar to the show storage wars, as people gain and lose money from mysterious objects.
