About ten minutes ago in dog years, this sort of tumble was strictly for movie stunt men. Now they’ve married a bouncy house on steroids and a crane, and everyone that’s got nerve enough to try it can fall with style. I humbly offer my marketing skills to help sell the thing to the masses: You’ve got to add a whoopee cushion sound to the big bag when they land on it. You’ll be richer than Disney in no time.
