Wish I could find it online but I can't. "BC" cartoon I saw as a kid. BC or one of the guys is walking along and comes across a sign that's fallen face down. He picks it up and the sign reads, "Put me down." Another: BC is digging a deep hole. Spying something at the bottom, he disappears out of view for a moment. He comes back up holding a human skull and shouts, "Okay, who's the wise guy!"
