Teleplay by Alfred Bester, from his story.
They are attempting to corrupt an incredibly sweet couple, the husband a handsome & honest architechtural designer who walks through the rain to vote, his wife a cutely beautiful girl who speaks three languages, designs & makes her own clothes, & goes to three different savings banks in one day to take advantage of sign-up promotions while cashing in her striped stamps. The first attempt is to put the husband in such a grumpy mood that he'd be likely to get drunk & cheat on his wife (w/ seductress Montgomery). The second attempt is to tempt the wife w/ an offer of $50,000 for a design drawing of a yacht done by her husband, but that by contract is the property of his employers. It has a twist ending that I won't reveal. A delightful and very funny show. The greatest part is seeing all the different personas that Astaire & Elizabeth get up to. I was able to buy a VHS copy from someone who runs an Elizabeth Montgomery tribute site and owns a 16mm print of the episode. Definitely worth watching more than once and going to some effort to find. A must-see "10" for anyone who likes these actors or who simply loves classy classic TV comedy.
