A grocer put up a sign that read "Eggplants, 25 cents each — three for a dollar."
All day long, customers came in exclaiming: "Don't be ridiculous! I should get four for a dollar!"
Meekly the grocer agreed and packaged four eggplants. The tailor next door had been watching these antics and finally asked the grocer, "Aren't you going to fix the mistake on your sign?"
"What mistake?" the grocer asked. "Before I put up that sign no one ever bought more than one eggplant."

Torbern Olof Bergman

Born 20 Mar 1735; died 8 Jul 1784 at age 49. Swedish mineralogist, chemist and naturalist who experimented with carbon dioxide, which he named aerial acid, and Joseph Priestley called fixed air. His investigation led him to successfully prepare artificial mineral water. In natural mineral water, he identified hydrogen sulphide. As a pioneer in chemical analysis, he introduced many improvements, studied minerals in particular and contributed to the theory of crystal structure. In 1775, his important paper Essay on Elective Attractions marked the beginning of his extensive work preparing affinity tables for acids and bases. By 1783, he ceased this effort due to failing health, leaving it to others to further develop an understanding of chemical affinity. He wrote an account of the use of the blowpipe in analysis.«
