verideon: please don\'t make such comments as \"where did you learn your english.\" Your english could use an improvement as well, but no one pointed that out... for example topic: \"I your smart youll know the answer\" should be \"If you\'re smart, you\'ll know the answer\" or something. It\'s annoying to see people get on each other for grammar, spelling and so on...
And as Adeli said, most likely everyone knew the answer... because (as faldrok said) that riddle is pretty old... \"pretty old\" being from sometime BC
