Funny stuff right there, especially the last one at the end http://alliancewake.com/video_details_extreme.php?id=4526
from time to time i have thought of making a cardboard wakeboard and see how long i could ride it or even make a contest out of it. while this is not quite limited to boards, it is still pretty cool and along the same lines.
...on another (but different) note, i for one am glad SS stuck with a black sole on the boots. ;)
