Several Muppet sketches took place in prehistoric times starring Ernie, paired with either Bert (as either his dad or his son) or Sherlock Hemlock (as "The Royal Smart Person"). Each one with Ernie and Bert contained a narrator, who would help translate their utterings of "ooga-mooga-mooga" and such. Later sketches were titled Caveman Days and Caveperson Days.


Caveman Kingdom

Picture Summary / EKA Description
(EKA: Episode 0300)
Everyone wants to go outside the cave, but they're not sure which way to go out until the Royal Smart Person invents an EXIT sign.
(EKA: Episode 0598)
King Ernie has a problem -- the cavemen write everything on rocks, which are too heavy to carry around. He calls upon the Royal Smart Person to invent something lighter to write on. (This sketch was adapted into a book, The Invention of Paper.)
(EKA: Episode 2414)
King Ernie needs to clean his yucky teeth. The Royal Smart Person brings a big brush (used for sweeping), then a middle-sized brush (used for brushing hair), then a smaller brush (used for painting), and finally a really small brush (a toothbrush). Just as Ernie proclaims that he'll "brush every tooth in the entire kingdom," a saber-toothed tiger comes in, seizes the toothbrush, and begins to use it himself! (The sabertooth in this sketch was the first puppet created by Ed Christie for a Henson-related production.)[1]
Something to Drink King Ernie wants something to drink, so he calls on the Royal Smart Person for help. The royal cow has quit, so there's no milk available. Ernie also shows that there is no liquid inside a rock or a stick. Then the Royal Smart Person suggests that Ernie should try squeezing a round orange thing (an orange), which turns out to have juice inside.
