A man went to his doctor, seek...
A man went to his doctor, seeking help for his terrible addiction to cigars. The doctor was quite familiar with his very compulsive patient, so recommended an unusual and quite drastic form of aversion therapy.
"When you go to bed tonight, take one of your cigars, unwrap it, and stick it completely up your butt. Then remove it, rewrap it, and place it back with all the others, in such a fashion as you can't tell which one it is. The aversion is obvious, you won't dare smoke any of them, not knowing which is the treated cigar."
"Thanks doc, I'll try it." And he did. But three weeks later he came back and saw the doctor again.
"What? My recommendation didn't work? It was supposed to be effective even in the most addictive of cases, such as yours is!" answered the doctor.
"Well, it kind of worked, doc. At least I was able to transfer my addiction," replied the patient.
"What is that supposed to mean?" demanded the doctor.
"Well, I don't smoke cigars anymore, but now I can't go to sleep at night unless I have a cigar shoved up my butt."

Gerald S. HawkinsDied 26 May 2003 at age 75 (born 20 Apr 1928).Gerald Stanley Hawkins was an English-American radio astronomer and mathematician who used a computer to show that Stonehenge was a prehistoric astronomical observatory. In the 18th century, William Stukely had noticed that the horseshoe of trilithons and 19 bluestones opened up in the direction of the midsummer sunrise. Hawkins identified 165 key points that correlated the stones and other archaeological features of the neolithic complex to the rising and setting positions of the sun and moon over an 18.6-year cycle. He first published his findings in an article, Stonehenge Decoded, in the journal Nature (1963), and then in a book with the same title (1965). In Beyond Stonehenge he explored the mysteries of Machu Pichu, the Nasca Lines, Easter Island and the Egyptian Temples of Karnak and Amon-Ra. In the 1990s, he studied the geometry of crop circles. |
