When the wise company president learned that his employees were tanking upon no-trace vodka martinis during their lunch hours, he issued the following memo:
To all employees; If you must drink during you lunch hours, please drink whiskey. It is better for our customers to know you're drunk than to think you're stupid.

First U.S. electric auto

In 1888, the first U.S. electric automobile, designed by Philip W. Pratt, was demonstrated in Boston, a tricycle powered by six Electrical Accumulator Company cells, weighing 90 pounds. Pratt held a number of patents as an inventor, the most significant being the first practical automatic fire sprinkler system (1872). His other inventions included furniture pads for chair leg tips (1878), a spring toy gun (1892), glazed target for vacuum-tipped toy arrows (1890), crutch (1901) and a bath mitten (1889). Some years earlier than Pratt's tricycle, in 1874, a three-wheeled electric vehicle had been built earlier by Sir David Salomons in Tunbridge Wells, England. It was a 1 h.p. device powered by Bunsen cells. By 1895, the first British manufacturer of electric cars was Acme & Immisch Electrical Works at Chalk Farm, London.«[Documentation on the 1888 tricycle is hard to find; only brief recent references found so far.
