Teasedale-Buckell tells an anecdote of a gent who once had a try gun session. When he had a gun made to the dimension, he couldn't hit anything with it. The gent complained, and the gunmaker began to explain that their records indicate that the gent was left-eye dominant, and... "But it's impossible that I should be left-eye dominant" - said the gent. "Why not?" - asked the maker. "Because my left eye is made of glass!"
