S1·E28 From Hopeless To Helpless, Part 1

O.J. Skweez comes to Sweet Polly Purebred with news about the Hopeless Diamond being worn at a party. Knowing that some crook is going to steal it, O.J. suggests that Polly will go to the party disguised as a waitress so she gets the first report of the theft. Meanwhile, Riff Raff also gets the news and plans to do the same thing exactly - disguise as a waiter to steal the diamond. Someone also gives Shoeshine Boy the news, telling him that he will have lots of shoes to shine at the party, although, Shoeshine Boy decides to go knowing there will be danger that will call for Underdog. At the party, Riff Raff unfortunately reveals himself when he runs into Polly. He takes Polly to the kitchen and decides to replace the Hopeless Diamond with ice. The lady who wears the diamond freaks out which sends in Underdog, who tells her that her diamond is actually ice. Meanwhile, Riff Raff (and his henchman Mooch) puts Polly in a car and rolls her downward.
