A guy sees an advertisement in a pet-shop window: "Talking Centipede $100."
The guy goes in and buys it. He gets home, opens the box and asks the centipede if he wants to go for a beer.
The centipede doesn't answer, so the guy closes the lid, convinced he's been swindled. Thirty minutes later he decides to try again.
He raises his voice and shouts, "Do you want to go for a beer?"
The centipede pokes his head out of the box and says, "Pipe down! I heard you the first time. I'm putting on my shoes!"

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.«
