Always hilarious, internet engineers have designated error code 418 as ‘I’m a teapot.’ It is returned by any internet-enabled teapots, which are sent a request to make coffee. It was introduced as part of the 1998 release of Hyper Text Coffee Pot Control Protocol (HTCPCP) specifications. Originally an April Fools’ joke, connected teapots have of course since been made and run according to HTCPCP. An attempt to remove this error in 2017 was defeated by the Save 418 Movement, which preserved it as ‘a reminder that the underlying processes of computers are still made by humans’.
