An old man was a witness in a burglary case in Miami. The   
defense lawyer asks Sam, "Did you see my client commit this   
burglary?"   

"Yes," said Sam, "I saw him plainly take the goods."   

The lawyer asks Sam again, "Sam, this happened at night. Are you   
sure you saw my client commit this crime?"   

"Yes" says Sam, "I saw him do it."   

Then the lawyer asks Sam, "Sam listen, you are 80 years old and   
your eye sight might be failing. Just how far can you see at   
night?"   

He quickly replied, "I can see the moon, how far is that?"
