A little boy comes home from his first bass lesson and his father asks, “So, how was your first lesson?” The little boy replies, “Oh, it was good. I learned that the top string is the E string and the next down is the A string.” His father is pleased.
The next day, when the boy comes home again, his father asks, “How was your lesson today?” The boy says, “Skipped it. I had a gig.”
