Two long-time golfing buddies...
Two long-time golfing buddies got to the course one day and decided that this day they would play the ball where it lies ... "No matter what!"
On the 14th hole, one of them sliced his drive and it ended up on the cart path. As he reached down to pick up his ball to get relief, his friend said, "Wait a minute! We agreed that we would not improve our lies! Remember? No matter what!"
The first player tried to explain that he was entitled to this relief, that it was in the rules of golf. But the second fellow would not allow it. Throwing up his hands in disgust, the man went to the cart and grabbed a club. As he stood near his ball, he took a few practice swings, each time scraping the club on the pavement and sending out showers of sparks. Finally, he took his shot. The club hit the path again, sparks went flying but his ball shot straight towards the green, landed and rolled to a stop two inches from the cup.
"Great shot!" his friend exclaimed. "What club did you use?"
The man gave him a wry smile, "Your 7 iron!"

He was the first person to undertake a systematic and comprehensive study of the ocean. His work on oceanography and navigation led to an international conference (Brussels, 1853) the first ever of its kind in the world. In 1855, during the Western gold rush, Maury's updated information helped sea captains cut a ship's average travel time from New York to San Francisco from 180 to 133 days. That same year, Maury prepared a report that proved the practicality - and assured the success - of the first trans-Atlantic cable between the United States and Europe.
