optics lec

larry: there are, of course, some people who have perfect 20/20 vision. those lucky bastards. for the rest of us myops, we can laugh that they will need reading glasses sooner than us.

some guy at the back throws a paper aeroplane
larry: that was pathetic. if u're gonna disrupt the lecture, at least make sure the aeroplane goes more than one row.
later... guy throws another one
larry: that was much better. it covered almost 3 rows i see. would you like to practice outside, perfect the skill, get the plane to actually reach me, and go to rmit to do aeronautical engineering?

larry: so what is the much anticipated and tough to calculate f point? (the answer is obviously 0)
lecture theatre: silence.
guy who threw the aeroplanes: it wasn't me!
(btw, no one saw any aeroplane flying, not even larry. but for some weird reason this is very funny.)
larry: whatever it was, it's good to know it's not you.
