“Old doughnut makers never die, they just get tired of the whole business”

“Old soldiers never die—they just fade away” is an old saying that was popularized by General Douglas MacArthur (1880-1964) in his farewell address to Congress on April 19, 1951. Many parodies of the saying have been made.
 
“Old doughnut makers never die, they just get tired of the (w)hole business” is a food joke on many Internet joke lists. The line “tired of the hole business” has been cited in print since at least 1959.
