5. Jews. Observant Jews and Jews whose parents are making them are about to embark on a week of eating a food that has become synonymous with cardboard. Tonight marks the beginning of Passover, a holiday that celebrates the exodus of the Jewish slaves from Egypt so that they could be free to choose to eat a cracker that looks and tastes like it has been intentionally burned. During the week of Passover, Jews don't eat bread or any other delicious, leavened foods. But 51 weeks of the year, free people choose bagels.
