What the...?

I ran across this bike Monday downtown. I have seen it before, but I've never been close enough to get a picture of it. I've even seen the rider "surfing" down the sidewalk by standing on the "saddle" and grabbing on to the uppermost bar ends (I need to get a picture of that someday).

As rickety as it looks (I spy some duct tape holding part of the handlebar "apparatus" together), I would guess that it rides like a nightmare.
