"Magazine editors are young. Otherwise nobody could sell them the jokes that had their day 40 years ago." — The Journal and Republican, Lowville, N.Y., May 15, 1930.
Along the same lines, from the Battle Creek (Mich.) Enquirer, Aug. 27, 1934:
"TODAY'S WORST JOKE
"Magazine Editor (to author): I'll give you 50 cents for this joke about President Roosevelt.
"Author: What's the matter? You gave me a dollar for the same joke about President Coolidge."
