Two aliens landed in the Arizona desert near a gas station that was closed for the night. They approached one of the gas pumps and the younger alien addressed it saying, "Greetings Earthling, we come in peace, take us to your leader".
The gas pump of course didn't respond.
The young alien became angry at the lack of response. The older alien said, I'd calm down if I were you".
The young alien ignored the warning and repeated, "Take us to your leader". Again no response.
Now, more annoyed, he drew his ray gun and stated, "Earthling, do not ignore us this way! Take us to your leader or I will fire".
The older alien warned his comrade again, saying, "You probably don't want to do that! I really don't think you should make him mad".
"Rubbish", replied the cocky young alien. He aimed his weapon at the pump and opened fire. The was a huge explosion. A massive fireball roared towards them and blew the young alien off his feet and deposited his burnt, smoking body into a cactus patch 200 yds away.
After about half an hour he slowly regained consciousness, refocused his three eyes, straightened out his antenna and looked dazedly at the old alien, who was standing over him shaking his big green head.....
"What a ferocious creature!" exclaimed the fried young alien, "He damned near killed me! How did you know he was so dangerous?"
The older alien leaned over, placed a friendly feeler on his crispy friend and replied, "If there's one thing I've learned during my intergalactic travels its, you don't want to mess with a guy who can loop his penis over his shoulder twice and then stick it in his ear"
