Watson' the IBM supercomputer, had a potty mouth.
Its memory was wiped out because programmers could find no other way to stop it from swearing.
Watson famously won Jeopardy! against the game show's human champions. It kept making obscene outbursts after memorizing the contents of the Urban Dictionary, a website that explains slang words.
Watson wasn’t able to master etiquette and good manners, so his masters were forced to delete the taboo vocabulary.
The research scientist in charge of tutoring Watson, had taught the computer the Urban Dictionary to help his communications seem more natural.
