Chemists in general are a crazy lot. I once worked in a lab where my job was to dispose of chemicals and clean out beakers and glassware (a dishwasher). Sometimes we needed to use concentrated sulfuric acid to clean out the particularly nasty stuff when regular detergent wouldn't cut it. One drop of this stuff will make your skin peel off and fall into the sink; one splash could blind you. I was always donned in a lab coat, thick gloves, safety glasses, etc. but my professor used just his bare hands, rotating the glassware so that the liquid would touch all surfaces. Meanwhile, I would watch in awe and wonder. Awe, because he was cocky enough to do this knowing the risks, and wonder, that he was still alive in once piece.
