Just found this gem on Twitters API...
When your app gets too excited they return status code 420 to tell you to chill! 😂😂😂

Fyi : For the non web-devs out there 420 is an invalid http code.

Almost forgot the link: https://dev.twitter.com/overview/...

Where is 418? Also 420 is not invalid.

@filthyranter 420 is not a valid response code (as in it's not in the HTTP spec). It's still a valid number but an un-official code so browsers etc do not recognize it. It either returns as 420 unkown or in the case of google chrome it gets converted to a 200.

Here you have it simplified.

My favorite is "I'm a teapot", not from Twitter, the rfc http error. :D
