In the 1920s, a "Dr. Lawson" offered a gadget you could rub on your body to erase fat. How about tapeworms you ingest on purpose to lose weight? And I'm not even going to describe what the Prostate Gland Warmer is like. These are part of the list of the 12 worst fitness inventions of all time at Men's Fitness. Pictured is the Battle Creek Vibratory Chair. Link -via Digg

The US flag has 13 stripes, to represent the original 13 colonies. The United States Postal Service always has stamps that depict the flag, although the design changes occasionally. On April 18, a new set of stamps were released, featuring four paintings of flags at different times of the day. The set is called "Flags 24/7". But wait! How many stripes does the fourth flag image have?

In the magnified view of the stamp image, there are 6 more stripes visible, before the image is clipped off. The small area located in the lower-left corner of the design is clearly white. By counting the stripes below the blue canton, starting with the white stripe (number 8) it is very evident that there is a 14th stripe and it is white.

This raises an even further design issue ... if the flag was bounded by red stripes as the top-most and bottom-most stripes, which every flag issued by the United States since the founding of the country in 1776 has been, it would leave one to think that the flag on the stamp, if it followed the usual red stripe convention, would actually have had 15 stripes!

If the Postal Service is forced to change the design, these stamps may become collectors items. Link -via the Presurfer

A farmer in Hooper, Utah built a fence out of old cars! Homeowners in a new subdivision were complaining about farming activities and the smell, but the neighbor who adjoins his property wouldn't help pay for a fence, so he built one from the material he had.

Creator Rhett Davis calls it his "Redneck Stonehenge." It's not that he doesn't like his neighbors, he's just not sure they understand him and his kind.

What used to be farmland is now filling up with subdivisions. "The unique community coming in, I don't think they're used to the farm life," Davis said. "I think the residential is starting to overpower the farmer."

A neighbor in one house complained about flies and smells and dust. The neighbor wouldn't pay half the cost of a fence, Davis says, so he built one himself with a Ford and two Toyotas stuck grill-first into the dirt.

"I kinda like them. I thought about putting Christmas lights on them," he said.

Griffin attempted to replicate, and even improve upon, a Super Aussie Burger.

I bought half a kilo of bacon, half a kilo of cheese, six eggs, lettuce, 3 tomatoes, an onion, beetroot, sesame seeds, mustard and ketchup, from Coles, the 4kg of mince from Fine Freddys' Meats again, and flavourings from my own kitchen. Total cost of the items bought was about $58.

It's the second project of the Giant Burger Project. Link -via Unique Daily
