You know that, I know that, but if everybody knows that you only have to enter the easier-to-read semi-nonsense word then ReCAPTCHA itself doesn't work so well for its larger purpose. And if you don't know that, then giving someone a CAPTCHA with Hebrew or a Rorschach inkblot in it when they're trying to buy Yo Gabba Gabba Live tickets for their four-year old is a surreal enough experience to make people think they're living in a situation comedy.
