An autistic boy in Texas who had never strung together more than a few words is now a bit of a YouTube sensation for doing far more than that. Jack Robbins, 8, stunned his parents when he began regularly singing the lyrics to Katy Perry's song "Roar" around the house, reports BuzzFeed. Mom Carla made a video of it, which quickly went viral. “I was completely amazed and so excited,” she says, reports Today.com. “For all these years, I’ve cooked for him, I put things on him, I dress him. I don’t know if he likes them or hates them. This is huge for me to finally know something that he likes.” See the Stir for more.
