This overheard occurred on Saturday 19th October, 2013
I was walking out of my local Tesco Express (like a Tesco Supermarket, but smaller) and overheard this snippet of conversation between two middle-aged women.
Woman 1 (puzzled): "I thought an underactive one would make you lose weight?"
Woman 2: "No, that's an overactive one... I've got an underactive one!"
