A sweet little boy surprised his grandmother one morning and brought her a cup of coffee. He made it himself and he was so proud. Anxiously, he waited to hear the verdict. The grandmother in all her life had never had such a bad cup of coffee. As she forced down the last sip, his grandmother noticed three of those little green army guys were in the bottom of the cup.

She asked, "Honey, why would three of your little army men be in the bottom of my cup?"

Her grandson replied, "You know grandma, it's like on TV. 'The best part of waking up is soldiers in your cup'."

First U.S. natural gas well

In 1815, the first developed natural gas well in the U.S. was discovered accidentally at Burning Springs during the digging of a salt brine well near Charleston, West Virginia. In the U.S., natural seepage had been observed centuries earlier in various places, but here, there was development and use of the natural gas and oil. In 1921, Fredonia, New York, the first gas well dug specifically for natural gas in the U.S. was drilled to 27 feet by gunsmith, William Hart to develop the seepage seen on the banks of Canadaway Creek. Early use was limited. The first industrial use of natural gas in the US was to evaporate brine for its salt, in 1841 by William Tompkins. Earlier, manufactured gas was first used in the U.S. for street lamps in Baltimore (1816).«
