It goes on to say:

One day later, Fish received a telegram asking him to send 24 cans of "Squibbly" for a market test immediately, signed by the same individual who had kicked him out. He called them back and explained that, after he had finished cleaning up his office, the two owners of Wham-O had come back to talk to him, and one had noticed a piece of the string on a lampshade he had overlooked while cleaning up. He explained where the string came from and the owners quickly asked him to send samples over for a market test.
