Here's an example of someone's first idea not working out as expected...
One of American's most popular snack foods, the potato chip was invented in 1953 by George Crum, a chef at the Moon Lake Lodge Resort in Saratoga Lake, New York, when one of his customers complained that their French-fried potatoes were too thick and mushy. As legend has it, Speck's solution was to thinly slice and fry some potatoes until brown, and the patrons loved what was to become the first-ever batch of chips.
