The Pickle

There was a guy on the beach with about 25 gorgeous chicks swarming all around him.
Seeing this, a second guy strolls on up to him and asks, "What's your secret?"
The guy whispers, "All you gotta do is stick a pickle in your pants."
In a fluorish, the second guy runs off and stuffs a pickle in his pants. But when he returns to the shore, he soon discovers that every single girl that looks his way, runs off screaming in bloody terror. Confused, he hurries over to the first guyand desperately asks, "Why are all the girls running away from me?"
The first guy looks up and replies, "The pickle's on the wrong side."

Giovanni Battista Donati

Born 16 Dec 1826; died 20 Sep 1873 at age 46.Italian astronomer who, on 5 Aug 1864, was first to observe the spectrum of a comet (Tempel 1864 II), showing not merely reflected sunlight but also spectral lines from luminous gas forming the comet tail when near the Sun. Earlier, he discovered the comet known as Donati's Comet at Florence, on 2 Jun 1858. When the comet was nearest the earth, its triple tail had an apparent length of 50°, more than half the distance from the horizon to the zenith and corresponding to the enormous linear figure of more than 72 million km (about 45 million mi). With an orbital period estimated at more than 2000 years, it will not return until about the year 4000.«
