The interested doctor
A concerned woman phones a doctor and says, "Doctor, I'm worried about my husband. He thinks he's a dog!"
"I'm coming over right away," the doctor says.
When the doctor arrives, the woman opens the door, and her husband, on all four, starts wagging his bottom and licking the doctor's hand.
"Interesting", the doctor says, startled. "I'll examine him. Make him lie down on the sofa."
"Doctor", the woman says, "I can't! He's not allowed the sofa!"

James ShortBorn 10 Jun 1710; died 14 Jun 1768 at age 58.British optician and astronomer who produced the first truly parabolic and elliptic (hence nearly distortionless) mirrors for reflecting telescopes. During his working life of over 35 years, Short made about 1,360 instruments - not only for customers in Britain but also for export: one is still preserved in Leningrad, another at Uppsala and several in America. Short was principal British collator and computer of the Transit of Venus observations made throughout the world on 6th June 1761. His instruments travelled on Endeavour with Captain Cook to observe the next Transit of Venus on 3rd June 1769, but Short died before this event took place.[Image: .Binocular Gregorian telescope by James Short, c. 1765, focal length 9.5 inches. Tubes numbered 275/1307 and 276/1308. The 275 and 276 are the numbers made of this focal length, and 1307 and 1308 are the total number of telescopes he made.] |
