The artist’s idea

The artist dreamed up an idea.
And he kept it in his head.
His agent sold the idea to a businessman.
“You own the idea,” said the artist to the businessman. “But you will never know it.”
“Brilliant concept!” said the businessman.
The next day, the artist went to the grocery store, where he was told he could pay for food he could never eat.
“Oh, is it for charity?” said the artist. “A food drive?”
“No,” said the grocer. ‘Thank you for shopping with us.”
The artist went home and starved to death.
The businessman sued the artist’s agent.
