New idea for CAPTCHA?

[lupus6x9]

I thought of this last night. I haven't seen anything like it, so maybe it's my original idea? (Don't have those often! )

I have seen CAPTCHA's that simply make you type the words in the image into the box, and I have seen ones that make you solve a math problem. But I haven't seen any yet that simply ask you generic knowledge questions, and so I think that this might be more difficult for a computer to crack. After all, computers can be programmed to try to "read" the phrase, regardless of the background, and they are designed, after all, to perform mathematical operations, but I think my idea might be better.

For example:

What fruit is named after the color of its peel? orange
What comes next in the pattern? One, ten, two, nine, three, _____. eight, 8
What is a very common four-legged household pet (three letters)? dog, cat, rat
What is the common name for floating white blobs in the sky? cloud
What color are the spots on a white cow? black
What animal makes the "oink" sound (three letters)? pig

Of course, it would check case-insensitively and be lenient enough to allow for punctuation in the answer as well as having a plural answer.

Yep, approaches like these make it very fun for the user. I've done a few of these before on some phpBB forums.
For example, I discovered http://justhumans.com/ about 2 weeks ago. Its very fun unlike a regular CAPTCHA which might just be annoying to some.

And a rat is a common household pet?

It was three letters. What if someone didn't think of "cat" or "dog"?!

Here's another one:

How many letters are in the answer to the question, "How many letters are in the word 'two?'" (just to really confuse them; the answer is five [5], obviously)

The problem with this type of captcha is that people are stupid.

Jay Leno went around asking people who the Vice President of the United States is (Dick Cheney, btw) and almost no one knew. See.

Actually, I considered adding a question, "Who was the first president of the United States?" but, seeing as not all users may be American, that could be a pain. But who DOESN'T know what color a white cow's spots are?!

Yeah, that would be very annoying. Someone who hasn't seen a cow before. (Lol, sorry)
I have a stupid idea, but how about adding "type this word backwords or in all case LOL."

Ok it took me ages to work out how there are 5!

That's a good idea, actually. And it's probably easier for most people, since there's no "trivia" involved (you know, since knowing the colors of a cow are TRIVIAL).

Yeash and what if you live in a country where there are no cows? And cows can also be just brown! (Edit: I see now, its white cows spots)
