This movie is hilarious. No other way to put it. I watched it today at my friends house and only now appreciated much of the humor, including the drugs and the gay cavemen. One especially funny scene is when the blind man was rubbing the Tyrannosaurus on the...ahem...and then whacked it with his cane. I rank this with Spaceballs as one of my all-time favorite movie spoofs. 10 out of 10.
