Any attempt to brew coffee with a teapot should result in the error code '418 I'm a teapot'. The resulting entity body may be short and stout.


The 418 I'm a teapot client error response code indicates that the server refuses to brew coffee because it is, permanently, a teapot. A combined coffee/tea pot that is temporarily out of coffee should instead return 503. This error is a reference to Hyper Text Coffee Pot Control Protocol defined in April Fools' jokes in 1998 and 2014.
