Big white badges that display the slogan, "Lose weight now. Ask me how." have been brought to my attention today and I want one. I think they're proudly worn by the WeightWatchers people. I'd like to have one just so that I can say to any inquisitive member of the general public, "Take that Mars bar out of your mouth, cut out fatty desserts and do some exercise!" Sorry, I should have more compassion. But if you need someone to tell you how to lose weight, then do heed my advice. If over Christmas you break a toilet seat by sitting on it, or observe your relatives having difficulty escaping from your gravitational field then do find one of these nice people with the big white badges.
