On the 4th of July, Americans will celebrate our country's 240th birthday.

One day earlier, a much more obscure anniversary will be observed.

Chubby and Bessie Woodman started running a small market in the town of Essex in Northeastern Massachusetts in 1914. Two years later, a guy who was hanging out in the shop joked that they should put a fried clam in the fryolator where they cooked potato chips.

The next day, July 3rd, 1916, they put a big sign out front saying "Essex Fried Clams."

"They sold them and they took in $35 that day, which was the most money they'd ever taken in in one day" explains Steve Woodman, the grandson of Chubby and Bessie and current proprietor of the shop, "They weren't stupid people - they kept them on the menu."

If you want to be a part of the festivities, you can visit Woodman's on July 3rd. Prepare for crowds, though, the restaurant is always busy on the July 4th weekend even when they aren't celebrating milestones.
