"Inside the Head" was a recurring Muppet segment on the Henson Company's television series CityKids. The segment features a cast of three Muppet characters based on Freudian ideas. The characters are shown in a spaceship-like control room that is actually the a working mind. The characters included the Captain, his Lieutenant, and the wild Libido. These characters embodied the Freudian principles of ego (Captain), super-ego (Lieutenant) and id (Libido). The concept of the segment is very similar to the proposed Starboppers television series developed by Jim Henson in the 1980s.
