Barney Google and Snuffy Smith, 11/13/23
You know, at first I thought this was about the eternal struggle between the modern scientific method, as represented by Doc Pritchart and his flatlander medical degree, and the ancient, chthonic folk wisdom of the Holler, as represented by Granny Creeps and her cave full of potions. But then I realized that Doc is probably just trying to stop Snuffy from getting poisoned. He's right to worry! Who the hell knows what's in that stuff she's going to give him!
