My math prof at University tells the class that if we can provide an acceptable explanation for this riddle, we get bonus marks. He also said that nobody has been able to solve it since he was in high school (a VERY long time ago). Have a go at it! I know there's no way I'll be able to solve it: Question: Why is a mouse when it spins? Answer: Because the higher the fewer. And yes, that is the exact correct grammer. Thanks. Jonny K.
