 Bart and Lisa Simpson track the puppies to Mr. Burns ' mansion , where they spy on him through a window . They see him treating the puppies well by giving them a bath . When one of the puppies stands on his hind legs , Mr. Burns picks him as his favorite of the bunch . Burns inexplicably claims that the puppy reminds him of actor Rory Calhoun , and names him " Little Monty " . After the bath , Mr. Burns walks into the next room , loads a gun , and sings a musical number called " See My Vest " ( a parody of " Be Our Guest " from the 1991 film Beauty and the Beast ) while demonstrating his wardrobe of fur clothing to his personal assistant , Waylon Smithers . After his performance , Burns prepares to kill all of the puppies , except for Little Monty , to make a new tuxedo for his wardrobe .
