A couple, the Browns, decide to find a therapist to spice up their love life. They finally decide on one that advertises he won't take your money unless he can help. They go to the appointment and have lengthy physical and psychological exams.
They meet the therapist and he says, "I believe I can help you". The Browns are ecstatic and listen intently.
He says to them, "Tonight, on your way home, I want you to stop at the grocery and buy grapes and donuts. When you get home I want you to both undress in the living room. Sir, I want you to roll the grapes on the floor with your nose, all the way across the room and into your wife's crotch. Then madam, I want you to take the donuts and see how many ringers you can score on your husband".
They call back in a few days to say their new games have really spiced things up. The Brown's are so happy, they tell their friends, the Smiths about it.
So they go to see the therapist. The therapist meets with them and says, "I'm sorry I cannot take your money as I cannot help you". They beg and beg, and finally the therapist gives in...
"On your way home tonight I want you to stop at the grocery and by apples and cheerios".

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).«
