Has a dining hall named after him, though that will only last for another year or so (probably to his relief).
He also likes to sing and play the guitar.

Has some highly spiffy stories, many of which are about physicists you've probably heard of. Often tells such stories during lab, to your amusement and distraction.
Also qualifies as a JediMaster?.
