Three musicians are killed in an automobile accident. They arrive together at the pearly gates, where they are greeted by Saint Peter.
“Hello,” says Saint Peter. “I suppose you’d like to get into Heaven!”
“Yes, we would,” says the first musician, a band director.
“Well, there’s just a little test you have to take. Nothing too difficult. Related to your earthly profession,” says Saint Peter.
“OK,” says the band director, “I’m ready.”
“How do you tune your band?” asks Saint Peter.
