In college I was taking a chemistry class.  The professor one day made an aside saying, "The Bible talks of Hell as being a lake of fire and brimstone.  Brimstone is sulfur.  Sulfur is a liquid between 266 degrees and 309 degrees Fahrenheit.  I just thought some of you might need to know this fact.  Now where was I?"  He then went back to his normal lecture.

That is a memorable way to sneak some theology into a college class.
