Apple Upsets Carl Sagan
In 1994, Apple codenamed the PowerMac 7100 "Carl Sagan." When the famous scientist discovered this, he sued Apple to change the name. Apple, in turn, renamed the computer "BHA," which stood for "butt-head astronomer." Very mature, Apple.
Once again, however, Sagan caught wind of this new name for the PowerMac 7100 and promptly sued the company for libel, but ultimately lost.
