Most of the newest cars have a Back-Up Sensor that warns the driver before the rear bumper actually comes in contact with something.

Most people probably think that this valuable feature came out of the minds of engineers but it was recently disclosed that the concept was first developed by a Chinese farmer.

His invention was simple and effective. It emits a high-pitched squeal when the vehicle backs into something.

One of the few things that was funny about some family members is a story when they were kids. They would visit their grandfather on the farm and the hogs were in their paddock. They would wait for the boar to go over to a post to scratch himself, they already had a stick in hand. He would start working is nuts on a post or cross beam at which point in time they would "swing for the fences" and send the hog squealing for the barn. Pretty soon grandpa would come out of the house asking if they were doing something wrong to which they would say no and have already stashed the stick. Before too long that boar would come out and start doing the same thing in which they would continue the game.
