Matty Benedetto runs a website called Unnecessary Invention but his latest seems very necessary these days. He calls it HookShot. It’s a coathook that pours you a drink when you hang up your coat. When you put your coat on the hook, a lever tilts a small bottle of booze into a shot glass, so that Happy Hour can begin practically the second you walk in the door. Unfortunately, Matty’s Useless Inventions aren’t for sale.
