I like your "I am a chemistry professor" as well. I busted up laughing. How often has that setup ever fallen in your lap? :-)
Well, it's usually followed by something disparaging of academics. But it fascinates me that some creationists really seem to believe that there are aspects to evolution that a chemistry or physics professor would determine are contrary to physical laws.
A few years ago, I had a proposal to review from an organic chemist who was making tiny molecular machines. It was beautiful work, but along the way he happened to mention that he believed some of the machines violated the second law.
Too bad. It looked like nice work.
