 As Bart and Lisa sneak away to Mr. Burns ' mansion , they see him loading a gun and singing a musical number called " See My Vest " , in which he proclaims his intention to kill the puppies to make a tuxedo out of them . When the staff discussed how they could gloss over the horrifying things Mr. Burns would do to the dogs , one of the writers suggested that if they communicated his plan through a song , it would stay " fun and light " . Scully , who agreed that the idea was good , came in the following day with complete lyrics that he wrote for " See My Vest " , which was a parody of the song " Be Our Guest " , sung by Jerry Orbach in the 1991 film Beauty and the Beast . Mirkin loved Scully 's work on the parody song , commenting , " The rhymes are really clever . It 's one of our very best songs [ on The Simpsons ] . " He also liked the fact that songs could be used in episodes of The Simpsons without the episodes turning into musicals , saying , " We 'll just do one song and that 's plenty . We have fun with that and then we 're out . "
