So the orcestra is on tour but the conductor takes sick. A call is sent out to the members of the orchestra to see if anyone can conduct. That evening one of the violist's comes up and says that he can conduct. He takes over and is brilliant, every show for the three months that it takes the conductor to recover the violist is conducting a storm. Eventually the conductor returns and the violist goes back to his partner who says, where have you been for the last three months?.
