A conductor tells a little joke:
Q: How do you know when there’s a harmonica player at the door?
A: He doesn’t have the key, he just comes in whenever he feels like it.
And the harmonica player returns the favour:
Q: Why are conductors’ hearts so coveted for transplants?
A: They’ve had so little use.
Q: What does a good conductor weigh?
A: 28 ounces, not counting the urn.
Q: What’s black and brown and looks good on a conductor?
A: A Doberman.
Q: A conductor and a violist are standing in the middle of the road. Which one do you run over first, and why?
A: The conductor. Business before pleasure.
