I Am A Tea Pot

HTTP 418 "I'm a teapot" was born as an April Fools' joke in 1998 and somehow made it into the official spec. It's literally the internet's way of saying "you're asking me to brew coffee but I'm a teapot, buddy." The joke is that this absurd status code—which should never exist in production—has become the web's most beloved meme response. It's like that one function in your codebase that was meant to be temporary but has been there for 6 years because everyone's too scared to remove it. The fact that some APIs actually implement it unironically is peak developer humor.
