Whispering Trees

It all started back in the Sixties when an advertising executive was sitting on his back porch, listening to the wind whisper through the trees.
“I’m listening to trees,” he said.
And that’s when the idea hit him: Trees that whisper advertising when the wind blows through them.
He mastered botany, genetics, grafting, and meteorology.
Then, he raised generation after generation of trees to perfect a single strain that whispered advertising.
“Eeeeeeat Hossssstesssss Twinkeeeeeeees,” whispered the tree.
By then, of course, Hostess had gone bankrupt.
So, the ad man used the trees for firewood.
They screamed curses as they burned.
