I went to the shop the other d...

I went to the shop the other day. I was only in there for about 5 minutes and when I came out, there was a damn traffic officer writing a parking ticket for over-running the meter.
So I went up to him and said,
"Come on, how about giving a man a break?"
He ignored me and continued writing the ticket.
So I called him a pencil-necked Nazi. He glared at me and started writing another ticket for also having parked partially on the pavement!!
So I called him a son of a mutant pig. He finished the second ticket and put it on the car with the first. Then he started writing a third ticket!!
This went on for about 20 minutes and the more I abused him, the more tickets he wrote. I didn't give a damn.
My car was parked around the corner...

Sir Ernst Boris Chain

Died 12 Aug 1979 at age 73 (born 19 Jun 1906). German-English biochemist who shared the 1945 Nobel Prize for Physiology or Medicine with Sir Alexander Fleming and Howard Walter Florey (later Baron Florey) for their work on penicillin. In 1928, Fleming had made the initial discovery of the antibiotic effect of penicillin. Being Jewish, Chain fled Nazi Germany to England in 1933. His varied research included phospholipids, snake venoms, tumour metabolism and lysozymes. From 1939, he worked with Florey on natural antibacterial agents produced by microorganisms, leading to their isolation, purification and determination of the chemical structure of penicillin. They performed the first clinical trials of the antibiotic. Chain's mother and sister perished in the Holocaust of WW II.«
