Beauregard Beauregard is the dim but lovable janitor at The Muppet Theatre who took over the mantle from George the Janitor beginning in of " The Muppet Show " . He also does duty as one of the Stagehands . Although he tries to be helpful , his dimwitted efforts frequently result in disaster . Affectionately known as Beau ( or Bo ) , his slow wit is often exploited by characters who use him to their own purposes . He has a characteristic blink and often turns to the camera and says , " " Right " . " Bo has superhuman strength , which is illustrated by his ability to effortlessly lift and carry around objects that are far too heavy to carry , such as an anvil , couch or piano . Beaker has occasionally assisted Beauregard with stagehand duties . Bo appeared onstage in various sketches and skits , including an appearance in the Veterinarian ' s Hospital sketch in . Other times , Beauregard appears accidentally on stage during productions , still working on the props until he realizes he is intruding and must either rush out of sight or attempt to blend in with the action . However , Bo was more comfortable backstage . It was here that a bunch of rats convinced him that he was an honorary rat , so that he would let them eat food out of the refrigerator ( ) . To his delight , they even elected him president . When Kermit delivered an ultimatum - - either the rats go or Beau does - - Beau heroically took the burden upon himself , offering to leave . However , Miss Piggy helped him realize how the rats were taking advantage of him , so he stayed . Beauregard originally wore a gray jacket over his plaid shirt , but sometime during the fourth season , he stopped wearing the jacket . Beauregard ' s most notable movie appearance was in " The Great Muppet Caper " , where he played a taxi driver . He brought Kermit , Fozzie and Gonzo to the Happiness Hotel - - and right through the front door , into the lobby . Bo makes an oft - quoted joke in the film - - when Kermit says that they ' ll catch the thieves red - handed , Bo asks , " What color are their hands now ? " It was also in this film that Beauregard once again displayed his heroic side by grappling with Nicky Holiday while the rest of the Muppets played " keep away " with the Fabulous Baseball Diamond . Bo ' s other major role was in the 1990 special " The Muppets at Walt Disney World " , where he dragged Miss Piggy onto a series of thrill rides . He has also made occasional cameo appearances in other Henson projects , including " The Muppets Take Manhattan " , " Muppets Tonight " , and " " . He had a brief , non - speaking cameo in the 2002 TV - movie " It ' s a Very Merry Muppet Christmas Movie " . Bo returned in a speaking role on Disney Xtreme Digital in 2009 , teaming up with Bobo the Bear in a series of videos called " Better Living with Bobo " . Beauregard also starred in a book , " Bo Saves the Show " . It ' s revealed in the 1984 stage show " " that he calls his mop " Belleregard . " The pair performed the Irving Berlin song " Cheek to Cheek " . In the book " Of Muppets and Men " , Dave Goelz explains that Beauregard was based on the clumsy Wendell Porcupine from " Emmet Otter ' s Jug - Band Christmas " . The main reason why Bo never became a star was because the writers thought he was too passive ; he didn ' t desire anything . This made Beauregard difficult to write for . In " The Muppets " , Bo was found sweeping up in a closet of the Muppet Theatre ; he had apparently been in there since the place was abandoned years prior , but was completely unaware of the theater ' s abandonment , asking Scooter where everybody had been . In " Muppets Most Wanted " , Bo is the engineer of the train that guides the Muppets through their world tour . Upon leaving Los Angeles , he starts the train going backwards . In ABC ' s Muppet series , Beauregard could be seen sweeping or mopping in the background , though he didn ' t have a speaking role . Merchandise . _ _ NOWYSIWYG _ _
