The Dentist

The dentist pulls out a Novocain needle to give the man a shot, so he can extract the man's tooth. 'No way! No needles. I hate needles' the patient said.
The dentist starts to hook up the nitrous oxide and the man objects I can't do the gas thing. The thought of having the gas mask on is suffocating to me! The dentist then asks the patient if he has any objection to taking a pill. 'No objection,' the patient says. 'I'm fine with pills.'
The dentist then returns and says, Here's a Viagra tablet.'
The patient says, 'Wow! I didn't know Viagra worked as a pain killer!'
It doesn't' said the dentist, 'but it's going to give you something to hold on to when I pull your tooth.

Pons Comet

In 1801, French astronomer Jean-Louis Pons (24 Sep 1761 - 14 Oct 1831) discovers his first comet. In his lifetime he discovered or co-discovered up to 37 comets. Since 1789, when he got a post at the Observatory at Marseilles as concierge, Pons quickly learned how to make observations with the instruments. He had a remarkable ability to remember the star fields he observed and to recognize changes. He logged his first discovery of a comet on 11 July 1801, which he had to share with Messier who found it a day later. Interestingly, as Pons' made his first comet discovery, that comet was Messier's last. Almost once every year, thereafter until 1827 when he eyesight declined, Pons found a new comet. Jean-Louis Pons set the record for visual discoveries of comets by an individual.
