Here's one...
When Tony Accardo was asked by the US Senate in Washington(in 1984 i think)about his association with Joey Aiuppa,Accardo said that he and Aiuppa were close friends for a long time and that they never discussed crime and that he never killed anyone.
Next question was:"Mr.Accardo,what does Mr.Auippa do for a living?"
Accardo said: "I dont know"
The whole court room started laughting
The Don kept his mouth shut also kept his innocent look of an old harmless man...
