"What is this thread about?" is a very appropriate question to ask on this thread. In fact, one could say that determining what this thread is about is the true reason for this thread's very existence. Sort of like a Philosophy professor asking "Why are we here?" and having some smartass from the back row answer "We are here to try to figure out why we're here."

Personally, I think Stephen Foster was the greatest philosopher of all time. It's been my experience that any vexing question can be answered by simply muttering, "Doo-dah... Doo-dah... Day." One might call it "The Zen of Doo-dah." But, then again, one might not.
