Things I learned from this movie:
1) Dirt never sticks to cavewomen, but it does stick to cavemen. Cavemen are, in fact, so dirty that it makes you wonder why cavewomen ever consented to be with them.
2) Cavewomen, by the way, are hot!
3) Giant Crabs will eat you if they have the chance.
4) Always be nice to dinosaurs if you can, they will become your friends and save you from a horrible fate.
5) Bondage is as old as man.
6) Bikinis are as old as man. (See also "One Million Years BC" for further details.) Also, they stay on under amazing situations, although only barely.
7) The words "Agoba" and particularly "AKEETA," were important linguistic developments in the history of speech.
8) In the time it takes a tidal wave to reach the shore, you have time to make a boat and fight over it with your arch-rival.
9) Never, never stand in front of a tidal wave, waving your arms about and trying to turn it back by magic. This will not work.
10) Cavewomen are HOT! Wait, did I say that already? OK, number 10 is: AKEETA!
In short, a priceless movie. Meaning that you should pay as little as possible to see it, but you should see it.
