Captcha with a twist - Are you a human being?

Most sites have a captcha check on forms where users can contribute input such as comments or forum posts. However Stackoverflow have added some twists to this otherwise standard mechanism - one sophisticated and one... not so sophisticated (but very humorous).

The sophisticated: By default there is no captcha - but if they cannot determine whether you are man or machine when you post your question/answer, they redirect you to the captcha page.

The humorous: Instead of just confronting the user with a standard captcha form, they have added a picture which must have been a lot of fun shooting, along with the following refreshingly down-to-earth text:

Are you a human being?
We apologize for the confusion, but we can't quite tell if you're a person or a script.

Please don't take this personally.
Bots and scripts can be remarkably lifelike these days!

Enter the CAPTCHA displayed below, and we'll be out of your way.


... great stuff.
