Stan Freberg in 1926.
He has a scroll of credits that would stretch from coast-to-coast, however, I will never forget this bit —
PAUL FREES: Radio? Why should I advertise on radio? There’s nothing to look at, no pictures…
STAN FREBERG: Look, you can do things on radio you couldn’t possibly do on tv.
FREES: That’ll be the day.
FREBERG: All right, watch this…ahem, okay people, now when I give you the cue, I want the 700 foot mountain of whipped cream to roll into Lake Michigan, which has been drained and filled with hot chocolate. Then the Royal Canadian Air Force will fly overhead towing a 10-tom maraschino cherry, which will be dropped into the whipped cream to the cheering of 25,000 extras. All right – cue the mountain!
