Ernie portrays Old King Cole.
(I had to make my own thumbnail for the following sketch):
Ernie the Caveman King wants something with which to clean his teeth.
Who better than Ernie to play a merry old soul like Old King Cole? While enjoyable, the first sketch is pretty straightforward, and I don't have much to say about it except that I have no idea how Ernie can blow bubbles, so don't ask me.
With regard to the second sketch, there were a handful of these "Caveman Days" sketches in which the
The Royal Smart Person is known outside of the caveman skits as Sherlock Hemlock, and I probably don't have to tell you that he's a parody of Sherlock Holmes. That was a distinction I had a hard time making as a kid, by the way. Since Sherlock Hemlock had all the iconic Holmes trappings, it took me a long time to understand that he was a parody of another, similarly named character. I remember someone, probably one of my older siblings, trying to explain it to me, and I was like, "What are you talking about? 'Sherlock Holmes'? That doesn't make sense; it doesn't even rhyme."
But I think my favorite character in this sketch is the Toulouse, the painter with the conspicuous French accent who paints on the wall of the cave. He's like a walking punchline; he embodies at least two jokes that would go right over most kids' heads.
I also particularly love the groovy theme music that plays at the beginning of this sketch and think it's hilarious how, since Ernie doesn't actually have any teeth, he ends up brushing his lips.
