If you are lucky enough not to live with a snarky millennial but fear you may be missing out on a whole world of sniping sarcasm, Ridley's Sarcastic 9 Ball will make a great addition. Ask it a question and you will be greeted by intellectual responses of the highest order: “well, duh!”, “Whatever” or “Yes, if you leave me alone” to name but a few. It will entertain and irritate in equal measure, rather like your average teenager.
