Mad TV did this alternate ending to the Wizard of Oz.
Power Risers
UPDATE: I have every reason to believe that the company is bogus. Do not order from them!
A few years ago, I saw someone at Decom wearing a crazy pair of stilts. He was jumping through the air as I tried to take his picture. I still have the picture at my desk. Today I finally ordered a pair for myself.
There are plenty of other videos on the stilts available elsewhere, just search on powerisers.
