of a conversation I had with a professor when I was in college.
I asked him: "WHY do I have to take humanities?"
His answer: "So you can hold your own a cocktail party."

Ed's comment about Don was:
Is there anything you don't have a working knowledge about?

Wow! What a nice compliment to Don!!
and without a doubt, well deserved!
I am grateful Don has a gift of willingness...
he investigates, absorbs, remembers and shares an amazing amount of information to all of us...
and I'd be willing to bet - he does QUITE well at cocktail parties
