Working on the theory that traffic always slows to a crawl when drivers want to get a good look at something, a Chinese grandmother who was fed up with people speeding through the crosswalk near her home came up with a rather unorthodox solution: She tied a blow-up doll to a tree on the corner.

But the unnamed woman did use a little discretion — she clothed the inflatable chick in a red negligee, complete with g-string. (Hey, she wanted motorists to slow down, not crash.)

And since her nefarious plot seems to be working, maybe we should lobby for American police to put down their speed guns and get busy, well, blowing. Selling photos of them hard at work on sex-doll inflation might just wipe out the national debt.
