A typical Gaudry lecture
person: can you move that overhead down? I cant see the top line.
Gaudry: blah blah, right hand derrivative.... what? Is something wrong?
person: yeah can you move the overhead?
Gaudry: Have I made a mistake somewhere? Is this the slide youre confused about? In this example what you do is just differnetiate-
person: no, I just wanted you to move the slide down so I can see it.
Guadry: Oh I see what you mean now, sorry about that, thats meant to be a three not a two, I'll just fix that up for you.
person: Can you just move that slide?
Gaudry: Ah now I know what you mean, *puts up old slide* Is that better?
I dunno how Im going to pass this subject
