This is an old advertising story. One that was told to me when I was a kid by my father. It predates all the Mad Man crap people seem to care about now.
One of Weightman's accounts was the baseball club, the woeful baseball club, the Philadelphia Athletics. These were the early days of TV when more seasoned agency people didn't want to work in the medium--they preferred print or radio, both of which were more prestigious than TV.
As the "kid" and the new kid, my father got the TV assignments. One of those assignments was to supervise the live commercials that would be announcer-read on post-game show after the Philadelphia A's games.
Post-game shows in the early days of television weren't that much different than post-game shows today. A player and an announcer would sit around and talk about the game. That was about it.
In any event Elmer was being interviewed and he crossed his legs. As he did, his pants rode up and revealed a large swath of skin between his shoes and the hem of his suit. This was de classe back in the early 1950s, and my father, responsible for the show reacted accordingly.
"Tell Elmer to pull his pants down," he stage-whispered.
Elmer didn't hear him. My father was sometimes easy to ignore.
"Elmer, pull your pants down." My old man was now shouting loud enough to be heard on the broadcast. "Elmer, pull your pants down."
For a short time my father was the Philadelphia pervert who wanted Elmer Valo to pull his pants down.
