Doug Mellard: Prophylactics

I remember one point, this older gentleman asked me for some prophylactics, and at that time, my sexual vocabulary wasnt that great, you know. So, Im checking my word bank for the closest thing I have to prophylactics. Closest thing I got -- pterodactyls. I was all confused. I was like, Excuse me, sir, I hate to break it to you, but those things have been extinct for 65 million years.

Charles Martin Hall

Born 6 Dec 1863; died 27 Dec 1914 at age 51.American chemist who invented the inexpensive electrolytic method of extracting aluminium from its ore, enabling the wide commercial use of this metal. While a young chemist, he experimented in a woodshed, intent upon finding a method for separating aluminum from its ore. At first, he was unsuccessful, but then realized that he needed a nonaqueous solvent for the aluminum oxide during electrolysis. On 23 Feb 1886, Hall found that molten cryolite (the mineral sodium aluminum fluoride) was a suitable solvent and using carbon electrodes with home-made batteries, he produced his first small globules of aluminum. By 1914, Hall's process had brought the cost of aluminium, once a precious metal used for fine jewelry, down to 18 cents a pound.«
