Millions of years ago, in stone age times, a cave man wakes up hurt and heads out to hunt for food with his trusty dinosaur for help. They come across some open water and spy Daffy Duck swimming and decide that he'd make a good meal - that was their first mistake.
This cartoon opens with a disclaimer that informs us that, for no great reason, this cartoon is set millions of years ago - just in case the audience can't guess that from the presence of cavemen and a dinosaur. This short features Daffy in `crazy' mood, which I always enjoy more than his bitter and cynical mood. The action is quite funny even if it isn't that imaginative at times.
The cave man sounds a little like Elmer Fudd and even vaguely resembles him to the point that I wondered why they didn't just get him in instead. Daffy is hilarious and is what makes the cartoon such fun, the dinosaur of the title doesn't have that much to do but has a few laughs - although he is a bit of a dumb animal.
Overall this is a good cartoon because I believe that any chance to see Daffy in crazy mood is worth a look even if the material is not as imaginative as it could have been.
