A drunk man who smelled like booze sat down on a bench next to a priest.The man's tie was stained, his face was plastered with red lipstick, and a half-empty bottle of gin was sticking out of his torn coat pocket. He opened his newspaper and began reading.
After a few minutes the man turned to the priest and asked,'Say Father, what causes arthritis?'
The priest replies, 'My Son, it's caused by loose living, being withcheap, wicked women, too much alcohol, contempt for your fellow man, sleeping around with prostitutes and lack of a bath.'
The drunk muttered in response, 'Well, I'll be damned,'then returned to his paper.
The priest, thinking about what he had said, nudged the manand apologized. 'I'm very sorry.
I didn't mean to come on so strong.How long have you had arthritis?
The drunk answered, 'I don't have it, Father.I was just reading here that the Pope does.

After visiting my Great Aunt...

After visiting my Great Aunt Annie, I travelled home in her old jalopy. The car was old and battered, it had a leak from the petrol tank, and I was stuck in second gear. This meant that I could only travel along at a steady 30 miles per hour and managed a paltry 20 miles per gallon of fuel. At the start of the journey I had placed exactly 10 gallons of fuel into the tank. I knew though, that the fuel tank lost fuel at the rate of half a gallon per hour. Just as I arrived home, the car stopped because it had run out of fuel and I had only just made it. How far was it from my Great Aunt's to my home?

Christian Konrad Sprengel

Born 22 Sep 1750; died 7 Apr 1816 at age 65. German botanist and teacher whose studies of sex in plants led him to a general theory of fertilization which, basically, is accepted today. Although director of a school at Spandau and tutor in Berlin, he devoted himself chiefly to the study of flowering plants. Sprengel's 1793 treatise [illustration at left] on floral structure examines the ways that flower colors, scents, shapes, and markings work harmoniously to attract insects for pollination. A clergyman and botanist, he spent his life researching the role played by the wind and insects in the fertilization of flowers. Although Sprengel's work was neglected by his contemporaries, Charles Darwin later praised Sprengel's work and brought it brought to public attention.
