Stan Weston, who...

...created G.I. Joe, died at age 84. From his New York Times obit (my emphasis):

As payment, Hasbro offered him $75,000 or a tiny royalty fee that was below the industry norm because he was new to the toy business, his daughter said. Eventually, he asked for $100,000, and Hasbro agreed.

“When he saw the line at the 1964 Toy Fair,” she said, “he knew he had made a mistake.”

The value of the copyright interests that Mr. Weston transferred to Hasbro later exceeded $100 million. Ouch.

Oh, and did I have a G.I. Joe? Are you kidding? Absolutely!
