Dancer, who is A.I. and why should he claim to have written A.E.'s riddle?

If you did this and enjoyed it, you can find tons of this sort of poser in a monthly magazine. I think it's called Logic Puzzles. Anyway there's a cartoon man sratching his head on the front inside a big letter Q and you'll find it in the puzzle magazine section of places like W H Smiths. They provide a grid for you to cross out all the impossible combinations which is the easiest way to solve the puzzle but it's more interesting to try and work it out without extra help !

i love doing those...or i used to...they all seem the same though...and i just don't have the time...i'll have to get one for the plane journey...

I don't believe for a second that Albert Einstein Wrote that question, and said the bit about 2% of the population being able to solve it...

It is so similar to other riddles I used to do when I was a kid - until I got bored with them, as you say they do seem to be all basically the same....
