A firefighter in Alberta, Canada thought he was ordering pizza from a local shop, but he mistaken called a pizza shop with a similar name in San Antonio, TX. Once the Canadian fire department recognized the mistake, they decided to donate the $300 order to local firefighters in San Antonio. Two stations in that city got 18 pizzas. The generosity has sparked an international pay-it-forward campaign -- #randomactsofpizza is trending on Twitter.
