You know what Ed, I said he did good with it and just thought others might have fun with it. I put pm me so others could see if they knew the answer before it was posted. I here all kinds of jokes and yes this was a riddle as Dan said. You use to give him shit also.

When I heard it I didnt even try to figure it out as I knew there was a stupid easy answer to it.

As far as Dan knowing the answer, Thats what a Mechanical Engineer is, A problem solver. Others PM'd me with the answer before Dan posted it. It was for fun not for you to come and say what you thought of me posting it.
