The Statue

A woman was in bed with her lover when she heard her husband opening the front door.
"Hurry!" she said. "Stand in the corner." She quickly rubbed baby oil all over him and then she dusted him with talcum powder. "Don't move until I tell you to," she whispered. "Just pretend you're a statue."
"What's this honey?" the husband inquired as he entered the room.
"Oh, its just a statue," she replied nonchalantly. "The Smiths bought one for their bedroom. I liked it so much, I got one for us too."
No more was said about the statue, not even later that night when they went to sleep. Around two in the morning the husband got out of bed, went to the kitchen and returned a while later with a sandwich and a glass of milk. "Here," he said to the 'statue', "eat something. I stood like an idiot at the Smith's for three days and nobody offered me so much as a glass of water".

Boston Philosophical Society

In 1683, the Boston Philosophical Society held its first meeting.* Rev. Increase Mather, stimulated by a recent comet sighting, and seeking to discuss how God intervenes in the natural order of things, had met earlier in the month with Samuel Willard and a few others to plan the group. Mather's idea was to model their meetings on the Royal Philosophical Society, established in London about 20 years earlier. Each last Monday of most of the following months, the members met and presented papers to emulate the transactions of the London society. However, the few local intellectuals didn't sustain interest in the society beyond about three years. Mather wrote Kometographia, or, A Discourse concerning Comets (1683).«[Image: Rev.
