So, did you find someone who was in the midst of moving, and just start shooting there? 'Cause that would be a lot of setup work otherwise.
I understand there are limits to what can be pulled off in the time available, but it felt like it needed to have more wacky stuff going on in the background -- more Pauls, another Graham entering in the background, seeing himself addressing the camera, and ducking back out again, Or you could have gone totally Escher and had a couple of Pauls working on the ceiling...
Very nice work.
