PHOENIX -- Some of our favorite talk-about stories today include a Texas father who wants a Fort Worth tattoo parlor shut down for piercing his 13-year-old's tongue. Three Northern California Walmarts have given up plastic bags in favor of reusable bags. Some Sumatran tigers in the wild were caught on infrared camera. And a sea lion leads a rescue team on quite the chase.
