Busy Bus Stop

In a crowded city at a busy bus stop, a woman who was waiting for a bus was wearing a tight leather skirt. As the bus stopped and it was her turn to get on, she became aware that her skirt was too tight to allow her leg to come up to the height of the first step of the bus. Slightly embarrassed and with a quick smile to the bus driver, she reached behind her to unzip her skirt a little, thinking that this would give her enough slack to raise her leg. 

Again, she tried to make the step only to discover she still couldn't. So, a little more embarrassed, she once again reached behind her to unzip her skirt a little more. For the second time, attempted the step, and, once again, and much to her chagrin, she could not raise her leg. With a little smile to the driver, she again reached behind to unzip a little more and again was unable to make the step.

About this time, a big man who was standing behind her picked her up easily by the waist and placed her gently on the step of the bus. 

She went ballistic and turned to the would-be Samaritan and screeched, "How dare you touch my body! I don't even know who you are!' The man smiled and drawled, "Well, ma'am, normally I would agree with you, but after you unzipped my fly three times, I kinda figured we was friends."

Cocaine anaesthetic

In 1884, cocaine was first used as a local anaesthetic to immobilize a patient's eye for eye surgery by Carl Koller. His success initiated the modern era of local anesthesia, with cocaine also quickly adopted for nose and throat surgery and for dentistry. For Koller, a Czech-born American ophthalmologist, the clue for this use was when he noticed that cocaine had a numbing effect on the tongue. He made many experiments on animals before introducing its use on humans. Cocaine was isolated in 1859 and was synthesized in 1885. It was later found with high doses or repeated use, it caused erosion of the corneal epithelium in high doses and it was replaced by less toxic, synthetic local anesthetics such as tetracaine and proparacaine.«
