B.C.: The First Thanksgiving(1973)

Overview

To add flavor to her rock soup, the Fat Broad commands Wiley, Peter, Thor, etc. to catch a turkey. The problem is that no one knows what a turkey is except for the turkey himself. In spite of this, the chase is on. Mostly a series of running gags, this animated special did a superb job of capturing the humor of Johnny Hart's B.C. comic strip.
