A guy goes to see the doctor...

A guy goes to see the doctor, because he's a little too well-endowed. In fact, it's 25 inches long and he can't get any women to have sex with him.
Anyway, the doctor says there's nothing he can do medically, but recommends a witch doctor that he thinks might be able to help.
The witch doctor takes a look at the problem and tells him to go to a particular pond, deep in the forest, and talk to a frog that lives there. "Ask the frog to marry you and each time the frog says no, you'll be 5 inches shorter."
Worth a try, he thinks, and off he dashes into the forest. He finds the pond and sees the frog on the other side, sitting on a log. "Frog, will you marry me?"
The frog looks at him, disinterested at best, and calls back, "No."
The guy looks down and sure enough, he's 5 inches shorter. Hey, this is great he thinks -- let's try that again. "Will you marry me?"
The frog rolls his eyes, and shouts back again, "No!"
Zappo! -- the guy's down to 15 inches. Well, that's still a bit excessive, he thinks. Down another 5 would be perfect. So he calls across again, "Frog, will you marry me?"
The irritated frog yells back, "Look..how many times do I have to tell you? No, No, NO!"

Anselme Payen

Born 6 Jan 1795; died 12 May 1871 at age 76.French chemist who made important contributions to industrial chemistry and discovered cellulose, a basic constituent of plant cells. His father's factories produced various chemicals, and refined sugar, so Payen studied science. In 1815, age 20, he was made manager of his father's plant for refining imported crude borax. There, he developed a synthesis for borax from soda and boric acid and in 1820 he created a new industry which could market the synthetic product at one-third the price of the refined natural borax. His father died in 1820, and Payen took over the family business. By 1822, he had found the value of animal charcoal to clarify sugar solutions. In 1833, Payen discovered the first enzyme, for which he coined the name diastase. It converts starch to sugar, and was later (1893) called amylase.
