The leader of a band was finding it extremely difficult to prepare for an important performance, because the members of the band were never all present at any one of the rehearsals. Then the last rehearsal before the show came, and again some of the members were not there. At the end of the rehearsal, the leader said to all the members of the band who were present, 'I have been making a note of those who have been absent from our various rehearsals. Here it is.' He took a piece of paper out of his pocket and looked at it. 'I see that the only man who has been hard-working and faithful enough to be present every time is the drummer.'
The drummer went very red, stood up and answered, 'Well, I thought it was the only right thing to do, as I won't be able to come to the show tomorrow.'
