Beauregard is the dim but lovable janitor at the Muppet Theater who took over the mantle from George the Janitor beginning in episode 310 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 episode 501. 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 (episode 503). 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.
He has also made occasional cameo appearances in other Henson projects, including The Muppets Take Manhattan, Muppets Tonight, and The Muppets: A Celebration of 30 Years. 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.
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 Theater; 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.
- Beauregard was also the name of a character from Walt Kelly's Pogo, a comic strip that influenced the development of Jim Henson's Muppet characters.
