<p>TheDad: I had a chemistry professor just like that; he was tall. We called him "Batman" because his wingspan tended to cover up most of the equations while he was writing them. All that we could see were the ends, and because some would meet in the middle, we were not even sure about matching up the ends. One day, after he turned around (as usual) and said "Got that?" someone took a photo.</p>
<p>P.S. we are getting OT, it seems.</p>
