M2MyEm: Thank you! That's very, very helpful! That makes much more sense to me.

Now I just have to figure out a way to get this info to the guy in a way that will persuade him to stop spouting nonsense AND that won't embarrass him. I don't want to make im feel bad; I just want him to stop using fake facts!

Thanks! (And BTW, further references or discussion are welcome! I'm not trying to shut this thread down or anything. I just wanted to say thanks. smile )
