A boy is listening to music on a stereo when his father walks over.

The father listens for a few seconds and then turns to his son, "Say, something is off about this song."
His son responds, "Are you sure?"
To which the father confidently nods and says,"Yep, there's a note out about it."

Edit:Not sure why this is marked as dirty.
