Don Knotts, who played Deputy Barney Fife on the Andy Griffith show, was born on this day. In one episode, the boys of Mayberry (Andy, Opie, Barney, Goober and Gomer) were gathered around the old fishing hole and everyone except Barney was scratching away at red bumps and welts on their arms and faces. ?You probably got into some poison ivy,? noted Barney. Andy replied, ?Well, you went where we went, so you should have it too.? ?Not really,? said Barney. ?I know how to avoid it.? ?Oh yeah,? Gomer chimed in, ?how's that?? ?Well, first, you gotta wear long pants and sleeves to protect your skin from the oil that starts it. I wear a barrier cream, too, called Ivy Block.? Andy asked, ?But what if you already have it?? ?Rinse with cool water, but don't scrub,? said Barney, ??cause it forces the irritant into your skin.? Listening intently, the boys noted Barney's fishing pole was hitting a bee hive and he was standing on an ant hill, but why tell him? He knew all about survival in the woods, right?
