Here is my idea.
Instead of using lame word CAPTCHAs, I want to build a CAPTCHA that pulls the aggregate most funny and least funny images from http://thefunniest.info/
The CAPTCHA will present the user with 3 images. Only one of them is funny.
I used to be against using CAPTCHA that could discriminate against taste or mentally retarded people, but if you don’t think this is funny, you must be a robot.
I wish http://thefunniest.info/ had an API so I could whip this up right now :(
