This is a puzzle which someone told me the other day. I have no solution as
yet - perhaps some of you creative types can come up with one.

	Two friends are walking down the street. One says to the other "Do
        you have any children?". The other replies "Yes - three sons".
 
        The first asks "How old are they?", to which the second replies

		"The sum of their ages is thirteen, the product of their ages
		 is as old as you are. The oldest weighs 61 pounds."

	How old are the three sons? For that matter how old is the friend?
	And what does the eldest weight have to do with anything???

	P.S. No discussions of weight and mass please - assume common usage.
