Is a mature adult really interested in good clean fun?"" Who's mature? What's fun? Or is ""impropriety the soul of wit"" (courtesy of Maugham)? Or is Ira Wallach (Hopalong-Freud and How to Pick a Wedlock) just a lie-down comic? He is and there's probably some commuter on the 5:07 who might enjoy the line ""Perhaps your hobby is picking your nose"" or some of the fancier clefts from entressage to crevissage while also boning up on positions, hard and software, exercises like breast-winking, aphrodisiacs, orgies (yclept fourzies) etc., etc. Oh well, ho hump.
