Change for a $15 bill

An incompentent counterfeiter spent all day making his funny money. At the end of the day he realizes he spent all his time making $15 bills.

He figures that the only way he's going to get anything from this batch of money, is to find a place where the people aren't too bright and change his phoney money for real cash.

He travels to a small town and walks into a small Mom and Pop grocery store. He goes to the old man behind the counter and asks him, "Do you have change for a $15 bill?"

The old man replies, "I sure do...How would you like that? An eight and a seven or two sixes and a three?"

John Michell

Died 21 Apr 1793 (born 1724). British geologist and astronomer who was first to devise a realistic estimate of the distance to the stars, discovered physical double stars, and is considered the father of seismology. After the Lisbon earthquake of 1755 (which killed 70,000 people), he suggested that earthquakes set up wave motion in the earth. He noted the increased frequency of earthquakes in volcanic areas. Michell realized that by comparing the time at which earthquakes are felt, the epicentre could be calculated. He invented a torsion balance, a device to measure very small forces, though died before carrying out its purpose to determine the density of the Earth. His rebuilt apparatus was used by Cavendish to make that measurement, which also gives the gravitational constant).«[Image: Michell torsion balance as used by Cavendish]
