Next on our countdown (I feel like Casey Kasem) is the third and final cartoon of the series. B.C.: The First Thanksgiving originally aired on NBC in the early 70s, but I didn't see it until the late '80s in syndication. The entire cast of the comic strip goes hunting for a turkey for their Thanksgiving soup, even though they don't know what a turkey is. Thank the Internet gods for YouTube, as it's probably the only place you'll see this obscure special; I don't believe it's in print.
