I was sitting on a plane minding my own business and getting set to read the book I brought. This guy sitting next to me introduces himself as Rickamaven. He then says he heard that long flights seem to go faster when you strike up a conversation with your fellow passenger. I asked Rick what he wanted to talk about. Of course he said politics since that was his favorite subject.
I said "Ok that is a good subject but let me ask you this first. A deer, a cow, and a horse all eat grass. But a deer excretes pellets, a cow a flat patty, and the horse dried grass. How can this be."
Rick looked a little perplexed and admitted he didn't know.
I said, "Well, how can you be qualified to talk about politics when you don't know ****." and returned to my book.
Sorry Rick had to do it. :o)
