The fact that this show aired many decades ago is obvious, when Doc Williams Frank Cady is finishing up a house call, and tells Ozzie and Thorny, "I think I'd better get back to my office. I have some cigarettes to test."
This story is about common illness, and Ozzie's belief that old-fashioned remedies are preferable to modern drugs. The modern cure prescribed by Doc Williams (Frank Cady) was called argipenicitin (Ricky calls it 'archie pelican seeds'), while Ozzie's preferred 'Old Fashioned' remedy was called Gaffney's Blood Tonic. (Both of these apparently were not actual medicines.) At the end of the show, Ozzie and Harriet appear from behind a stage curtain in a rare Epilog to assure the audience (and doctors) that they were only having a bit of fun - and to remind viewers that their regular sponsor, Listerine, is a real cold remedy.
This program marked the first appearance of Doc Williams, played by Frank Cady.
