Two aliens landed in the Arizo...

Two aliens landed in the Arizona desert near a gas station that wasclosed for the night. They approached one of the gas pumps and the youngeralien addressed it saying, 'Greetings, Earthling. We come in peace. Take us to your leader.'
The gas pump, of course, didn't respond.
The younger alien became angry at the lack of response.
The older alien said, 'I'd calm down if I were you.'
The younger alien ignored the warning and repeated his greeting. Again, there was no response.
Annoyed by what he perceived to be the pump's haughty attitude, he drew his ray gun and said impatiently, 'Greetings, Earthling. We come inpeace. Do not ignore us this way! Take us to your leader or I will fire!'
The older alien again warned his comrade saying, 'You probably don'twant to do that! I really don't think you should make him mad.'
'Rubbish,' replied the cocky, young alien. He aimed his weapon at thepump and opened fire. There was a huge explosion. A massive fireball roared towards them and blew the younger alien off his feet and deposited him a burnt, smoking mess about 200 yards away in a cactus patch.
Half an hour passed. When he finally regained consciousness, he refocused his three eyes, straightened his bent antenna, and looked dazedly at the older, wiser alien who was standing over him shaking his big, green head.
'What a ferocious creature!' exclaimed the young, fried alien. 'He damn near killed me! How did you know he was so dangerous?'
The older alien leaned over, placed a friendly feeler on his crispyfriend and replied, 'If there's one thing I've learned during my intergalactic travels, you don't want to mess with a guy who can loop his pen*sover his shoulder twice and then stick it in his ear.'

Carl Koller

Born 3 Dec 1857; died 21 Mar 1944 at age 86.Czech-born American ophthalmic surgeon whose introduction of cocaine as a surface anesthetic in eye surgery on 16 Sep 1884 inaugurated the modern era of local anesthesia. He was a colleague of Sigmund Freud, who in 1884 was interested in the use of cocaine to cure morphine addiction. Koller noticed cocaine had a numbing effect on the tongue and, after experimenting with animals, introduced it as a local anaesthetic in ophthalmology. It was also quickly adopted for nose and throat surgery and for dentistry. Cocaine was isolated in 1859 and was synthesized in 1885. It became evident that this agent produced erosion of the corneal epithelium in high doses or with repeated use. Later, less toxic, synthetic local anesthetics such as tetracaine and proparacaine were developed.
