I dunno, this may be the most bonkers skate video you've ever seen. It starts a bit slow but stick with it: Bob Burnquist shows us what he can do on his backyard MegaRamp.
This video is also a fantastic demonstration of the principle of Chekhov's helicopter, which states that if you see a helicopter sitting next to a MegaRamp in the first two minutes of a skate video, a skater must absolutely drop in to the MegaRamp from the helicopter in the last part of the video.
