Bob & Ray For the Truly Desperate (1946~1988)

Bob and Ray were an American comedy duo whose career spanned five decades, composed of comedians Bob Elliott (1923–2016) and Ray Goulding (1922–1990). The duo's format was typically to satirize the medium in which they were performing, such as conducting radio or television interviews, with off-the-wall dialogue presented in a generally deadpan style as though it were a serious broadcast.

Commercial parody was a popular forte with Bob and Ray. A typical show would have such "sponsors" as:

• The Monongahela Metal Foundry ("Casting steel ingots with the housewife in mind")
• Einbinder Flypaper ("The brand you've gradually grown to trust over the course of three generations")
• The Auburn Motor Car Company ("Makers of fine automobiles up to, but not including, 1938")
• The United States Post Office ("Makers and distributors of stamps")
• The Croftweiler Industrial Cartel ("Makers of all sorts of stuff, made out of everything")
• Cool Canadian Air ("Packed fresh every day in the Hudson Bay and shipped to your door")
• Grime ("The magic shortening that spreads like lard")
• The United States Mint ("One of the nation's leading producers of genuine U.S. currency")
• Penuche ("With or without nuts, the greatest name in fudge")
• Kretchford Braid and Tassel ("Next time you think of braid or tassel, rush into your neighborhood store and shout, 'Kretchford'!")
• Chocolate Cookies with White Stuff In Between (sponsoring Lawrence Fechtenberger)
• Gerstmeyer's Puppy Kibbles ("The dog food guaranteed to turn any pet into a vicious man-killer"), sponsoring the police-drama spoof Squad Car 119.
• Mushies ("The cereal that gets soggy even without adding milk or cream") sponsored "Tippy the Wonder Dog".
• An unnamed beverage described as "stuff that you pour in a glass and it fizzes up and gets all over your suit and everything".
