Back when Apple was designing their fancy new
Power Macs, they had a code name for each of them. The entry-level 6100 was code-named
Piltdown Man (a hoax), the high-end 8100 was code-named
Cold Fusion (another hoax), and the middle-of-the-road 7100 was called
Carl Sagan (errr, not a hoax).
In a magazine article, Carl Sagan read his name used in connection with a product along with two hoaxes and fired off an angry letter demanding that his name be removed from the product, and that he would never allow his name to be used as a form of endorsement, especially without getting paid.
Apple's engineers complied, and the code name of the Power Mac 7100 was changed to BHA.
Word got out that BHA stood for Butthead Astronomer, so Sagan sued for libel, demanding once again that Apple's engineers change their internal code-name.
They complied once more, taking the advice of Apple's legal department, changing the name to LAW, for Lawyers are Wimps.
Carl Sagan continued with his libel suit, which was thrown out.
