The Deaf Mafia Bookkeeper

A mafia Godfather finds out that his bookkeeper of 20 years, Guido, has cheated him out of $10 million. Guido is deaf which is why he got the job in the first place. The Godfather assumed that since Guido could not hear anything, he could never testify in court.When the Godfather goes to confront Guido about his missing $10 million, he takes along his personal lawyer because he knows sign language.

The Godfather tells the lawyer, "Ask him where the money is!"

The lawyer, using sign language, asks Guido, "Where's the money?"

Guido signs back, "I don't know what you are talking about." The lawyer tells the Godfather, "He says he doesn't know what you are talking about."

The Godfather pulls out a pistol, puts it to Guido's head and says, "Ask him again or I'll kill him!"

The lawyer signs to Guido, "He'll kill you if you don't tell him." Guido trembles and signs back, "OK! You win! The money is in a brown briefcase, buried behind the shed at my cousin Bruno's house."

The Godfather asks the lawyer, "What did he say?"

The lawyer replies, "He says you don't have the balls to pull the trigger."

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]
