Two Aliens land in Detroit, ne...

Two Aliens land in Detroit, next to a Gas station. The Aliens waddle out of their ship and look around. The first thing they see that resembles a being is the Gas pump. The two Aliens approach.
The first one says, "Earthling take me to your leader!" He gets no response.
The first Alien looks at his buddy then addresses the pump again, "Earthling, I said Take me to your leader!" Still no response.
The first Alien then turns to the second and says, "If this Earthling doesn't show me some respect I'm going to blast him!"
The second Alien replies, "O.K. but, I'm just going to stand down on the next block."
The first Alien looks a little puzzled, but waits for the other to waddle to the next block. He then addresses pump a third time,"Earthling take me to your leader!" No response.
The Alien then pulls out his ray-gun and shoots the pump...
After the explosion the Alien gets up, dusts himself off then goes down the block to his buddy.He then says to the second Alien, "If you knew that was going to happen why didn't you warn me?"
The second replies, "I didn't know what was going to happen, but I'm not going to mess with anyone who can hang his penis to the ground, wrap it around his body twice, and can still stick it in his ear!"

Baron Wilhelm von Biela

Born 19 Mar 1782; died 18 Feb 1856 at age 73.Austrian astronomer who was known for his measurement (1826) of a previously known comet as having an orbital period of 6.6 years. Subsequently, known as Biela's Comet, it was observed to break in two (1846), and in 1852 the fragments returned as widely separated twin comets that were not seen again. However, in 1872 and 1885, bright meteor showers (known as Andromedids, or Bielids) were observed when the Earth crossed the path of the comet's known orbit. This observation provided the first concrete evidence for the idea that some meteors are composed of fragments of disintegrated comets.
