*fond sigh* ok but I am completely in love with the concept of John using small portions of his ground-time to lecture at local/not-so-local university/colleges. He does talks on astrophysics or space life or laser communications or whatever they happen to need a guest lecturer for, and gets all flustered when he has all these brilliant students quoting his dissertations including the one Scott likes to use as a doorstop back at him and quizzing him on the finer details of the Tracy Quasar. The glasses are correcting for atmospheric pressure. Very scientific and not at all aesthetic I promise. ;) <33
