More on the topic of poor preparation.
I was at a social function wherein the host had to entertain some foreign visitors. He wanted to show them a movie, but he didn't have the right DVD on hand.
This other fella -- a guy who had been tapped to help out with the event -- said, "Oh, no problem. We'll just go to Netflix and play the movie that way." Obviously, that was a poorly conceived idea; after all, Netflix streaming can be erratic at best. Unless you're lucky, it won't make for a smooth experience, and there's a very good chance that the movie might not be available.
This fella has a habit of coming up with half-baked solutions -- essentially bandages in place of proper fixes.
