New Guy in Town

The new guy in town decided to take a few minutes and head down to the local pub to try to meet some people. He stumbled in at about 7 PM and sat down at the bar to order his first drink.

One of the regulars sitting at the pool table got up and came over to start up a conversation. He says, "hey, I bet you 5 dollars I can lick my eye". The new guy was a little put-off by this introduction, but it was early in the evening so he took the bet. Sure enough, the regular had a glass eye, popped it out, licked it, and put in place.

A funny enough parlor joke, he handed the man 5 dollars and went back to drinking. A few minutes later he returned, this time saying "I bet you 5 dollars I can touch my elbow to the back of my head." Desparate for any attention, the new guy handed over another 5 dollars and watched as the regular popped his shoulder out of joint and touched the back of his head.

Deciding he had already duped the new guy out of $10, the regular headed back over the pool table for the next few hours. As the bartender began to close up shop, he returned for one last wager. "hey, I bet you $100 I can piss on the celing". The new guy looked up at the vaulted ceiling which was eaily 30 feet above and was convince he would soon win his money back and a nights worth of drinking.

The regular pulled it out but didnt even come close, pissing on the bar and the local guy. "Ha! I won all my money back! That was a stupid bet!"

The regular retorted, "yeah, but I bet the guys over there $500 I could piss on you and make you laugh!"

1,000th pulsar

In 1998, the discovery of the 1,000th pulsar in our galaxy was announced in a press release by the Jodrell Bank Observatory, University of Manchester, using the 64-meter Parkes Radio Telescope in New South Wales, Australia. A “multibeam”receiver was installed on the telescope in early 1997. This allowed the astronomers from England, Australia, United States, and Italy to find pulsars much faster than before. On average, they found a new pulsar in every hour of observing. By this date, the researchers had found more than 200 pulsars and they expected to find another 600 more before the survey ended. The “multibeam”receiver used consists of 13 hexagonally arranged receivers that allow simultaneous observations.
