The Vase

A guy goes to a girl's house for the first time, and she shows him into the living room. She excuses herself to go to the kitchen to make them a few drinks, and as he's standing there alone, he notices a cute little vase on the mantel. He picks it up, and as he's looking at it, she walks back in.
He says "What's this?"
She says, "Oh, my father's ashes are in there."
He says, "Jeez...oooh....I..."
She says, "Yeah, he's too lazy to go to the kitchen to get an ashtray."

Ozone layer

In 1995, Americans Mario Molina and Sherwood Rowland, and Dutch scientist Paul Crutzen won the Nobel Prize in chemistry for their work warning that CFCs are eating away Earth's ozone layer. In 1970, Dr. Crutzen showed that nitrogen oxides are important in the natural balance of ozone in the upper atmosphere. Thus research rapidly escalated into global biogeochemical cycles. In 1974, Drs. Molina and Rowland established that there was a threat to the ozone layer from man-made chlorofluorocarbons (CFCs), such as gases then used in spray cans. More than a decade before the Antarctic ozone hole was discovered, their research stirred the international response to control the emissions of CFCs to protect the ozone layer.
