CRAPCHA
An embeddable way to annoy visitors to your site: CRAPCHA.
CRAPCHA is an acronym for Completely Ridiculous And Phony Captcha that Hassles for Amusement. It is a parody of the annoying CAPTCHA codes that try to verify that you are not a bot. […] CRAPCHA takes this to the next level, with characters that are impossible to reproduce.
