(What was it you told me that time when I posted the same thing twice? Something about losin' my memory?)
I have to agree with you about the rocket launcher scene. It's one of my favorite comedy scenes in the entire series, and it's also an example of perfect timing and duration. It could have been drawn out into a longer scene, but those few seconds were almost perfect. The only thing I would've changed if I had have been the director might have been Wood actually seeing enough of the action to recognize the threat, but not Buffy, and diving under the desk, where Buffy would find him cowering the next morning.
