Im setting up a captcha and using a question and answer system.
Anyone have any suggestions of questions to ask that are hard for bot software to work out but easy for a human.

Personally I prefer the simpler to read two words or numbers. I wonder how important it is for captchas to be so distorted that it takes about 5 attempts to get them right.
More and more seem to go for words that are random but easily read, like 'toaster wingnut' or ' mangrove helicopter'
edit: I think those two are from Monty Python lol
There's the answer! random Monty Python names.
The best way forward is custom questions which cant be googled. I just had to change some captchas as they got cracked in the latest spam software.

Silly questions indeed. When I was a child, phones didn't have area codes.
If they answer no you should be good to go
Yes same here and the where did they meet question, well I was only a twinkle in their eyes.
You can of course answer any old rubbish and screenprint it.
What is the very precious metal used for coins that isn't silver?
What is the colour of grass?
What is the colour of cochineal?
(These are "challenge questions", BTW - nothing to do with CAPTCHA.)
To make it harder for the "bots", present these questions as an image of the text.
Does anyone manage to use the audio playback hint and actually hear the words? all I hear is garbled ghostly sounds.
well I would be screwed as my parents did not have a phone line until I had left home.
what daft questions - I find the ones where they have random animals and you have to pick out a cat are easy to use and at the same time difficult for a Computer to work out the correct answer.
