Today, April 22nd, is National Jelly Bean Day. The origin of the Jelly Bean is as mysterious as the origin of National Jelly Bean Day. Some say the Jelly Bean was created by a dentist who was short on cavities so he opened a bakery and confectionery store to feed his habit of extracting more money from his customers. The urban legend goes on to say the now infamous, filthy and rich dentist realized that the jam fillings in his iced cupcakes was not enough so he created the jellybean. The rest is oral history.
