Celestial navigation

From Willipedia

Go to Williams-Mystic and learn how to celestially navigate yourself, so that if you are ever in a lost boat in the open ocean--or really lost anywhere, for that matter--you can figure out what direction you're facing. (And, if you happen to have several appropriate books of charts, a sextant, a couple of triangles, compass, navigation paper, and an extremely accurate watch, pinpoint your exact latitude and longitude).

Or, at least, be able to name lots of stars and constellations, so that you can hit on someone by offering to take them stargazing.

Taken with Don Tweorgy, a man whose voice could do work for Nova, whose patience rivals your kindergarden teacher's, and whose jokes would not get him anywhere.

Meets once a week for two hours that fly by.
