RE: No, you can go ballacks. Ooooh, Jay please tell us that story about Stockport hat makers and their use of mercury nitrate, pleeeeeaaaaaase.
Mad as a hatter, like Rosco said derives from the fact that hat makers used mercury to give the Top Hats they produced that silvery sheen. Prolonged exposure to mercury sends your brain daft. Hence, mad as a hatter. Hurrah, you got it out of me in the end!
