Maxim.com senior editor Justin Halpern sold his popular Twitter postings–turned–book, Shit My Dad Says, to Kate Hamill at It Books, who took world English rights at auction. The collection of gruff, funny and sometimes sneakily heartfelt musings from the author’s 73-year-old dad got Halpern an online audience of more than 300,000 as well as press hits from papers like the Wall Street Journal and L.A. Times. Agent Byrd Leavell of the Waxman Agency said the book, slated to pub next Father’s Day, will also feature “longer stories in a David Sedaris, Chelsea Handler vein.”
