A violist comes home late at night to discover fire trucks, police cars, and a smoking crater where his house used to be.
The chief of police comes over to him and tells him, "While you were out, the conductor came to your house, killed your family, and burned the house down."
The violist replied, "You’re kidding! The conductor came to my house?"
