Finally, a law that makes sense to all of us. It has long been the law in Philadelphia that you can be arrested for selling pretzels in bags. If you sell the pretzel wrapped only in a napkin, however, you are in for a perfectly legal treat. This law was made during the prohibition, where “pretzels” were often sold in paper bags, and illegal alcohol accidentally found its way into the bag as well. While this law can technically still be enforced, it is unlikely that you will be arrested for your heinous crime.
