Justin Halpern. Halpern created the Twitter account "S--- My Dad Says" in 2009 to share it with the world. Two months later, he had millions of followers (the count now sits at 3.1 million) and a book deal with HarperCollins. That book hit No. 1 on the New York Times bestseller list and led to a short-lived CBS sitcom, "$#*! My Dad Says," starring William Shatner. Halpern still tweets out his dad's best moments.
