Hercule Poirot is a fictional detective created by Agatha Christie in 1920 whose exploits have been filmed many times, including a series of movies starring The Muppet Show guest star Peter Ustinov. The character (and other works by the author) have occasionally been spoofed or referenced in Muppet productions.

• Jason Alexander portrayed Poirot in episode 108 of Muppets Tonight, in "Murder on the Disoriented Express", spoofing the best known film based on the Poirot books. The passengers, including Dr. Bunsen Honeydew and Bobo the Bear, frustrate Alexander by confusing the detective with the Greek demigod Hercules (and very briefly, Superman).
• Bag dresses as Poirot, joining Chelli as Sherlock Holmes, to play detective in an episode of Big Bag.
