A musical director was having a lot of trouble with one drummer.
He talked and talked and talked with the drummer, but his
performance simply didn't improve.

Finally, before the whole orchestra, he said, "When a musician
just can't handle his instrument and doesn't improve when given
help, they take away the instrument, and give him two sticks, and
make him a drummer."

A stage whisper was heard from the percussion section: "And if he
can't handle even that, they take away one of his sticks and make
him a conductor."
