Not a joke but a pardox. Try to get your heads round this:- A woman out with her toddler when an aiigator. The women pleads with the the aligator. "Give my child back" She cries. The aligator reply. "I will give you your baby back if you tell me what I am going to do with the child" "You are going to eat him" She said, hoping to clear this up. Here is the problem. If she is right the the aligato must give the child back, this would mean that she wrong so he will eat the child making her right. PHEW!! And so it goes on.
