Three old men

Three old men are talking about their aches, pains and bodily dysfunctions.

One 75-year-old man says: "I have this problem. I wake up every morning at 7 a.m. and it takes me 20 minutes to pee."

An 80-year-old man says: "My case is worse. I get up at 8 a.m. and I sit there and grunt and groan for half an hour before I finally have a bowel movement."

The 90-year-old man says: "Not me. At 7 a.m. I pee like a horse and at 8 a.m. I crap like a cow."

"So what's your problem?" asked the others.

"I don't wake up until 9:00."

Willson was attempting to produce metallic calcium from coal tar and burnt chalk (lime) in the furnace with which he hoped to reduce aluminium oxide to produce aluminium, the goal of their business. Instead, by chance, he found a hard crystalline solid, which gave off a gas when dropped in water. The gas burned with a bright, smoky flame. A sample was tested by Dr. Venable, Morehead's chemistry professor. He identified the calcium carbide and acetylene gas. This discovery eventually led to the formation of Union Carbide Company, which Morehead cofounded.«
