Created by Matty Benedetto of Unnecessary Inventions, the Passive-Aggressive Punching Bag affixes to the side of your desk and plugs into your computer, generating a randomly selected passive-aggressive opening line to emails with a simple punch. A great idea, I just wish it continued to compose an angry email the more you punched, then sent a convincing malware attachment to the recipient when you tore the bag open and started chewing the stuffing.
