What do you get the man who has everything? How about his own private sidewalk? No better way to avoid the gum and dog doo — plus, the ambulatory pavement is scary enough that people will prostrate themselves beside you and say:
“Stranger — though you are nothing like mortal men in shape or stature, but are as the deathless gods — hail and all happiness to you, and may the gods give you good.”
You have to walk really slow, though.
Given that this video was shot four years ago (when Google Video was the business), I’m guessing this idea never took off.
