Did you know that bluetooth is named after King Harald 'Bluetooth' of Denmark. Supposedly because he succeeded in getting the tribes of Denmark to communicate with each other and unite with each other? This in spite of the fact that a meaningful modern "kingdom" as we would understand the term didn't really emerge until another 50 years or so after his death and in fact he simply consolidated the Jutland peninsula? When I try to make my computer and my speakers communicate with each other I can tell.

Also he was ovethrown and forced into exile by his own son for being so crap. The son, Sveyn Forkbeard, would later go on to conquer, and become king of, England (which actually was a real kingdom already). Bluetooth has been giving me shit for over a thousand years.
