Bassist Joke!
Little Johnny's father finally agrees to teach him to play bass, just like his dad. For the first lesson, Dad shows Johnny the E string and tells him to practice thumping on just that string. Nice, even quarter notes. For the second lesson, Dad shows Johnny the A string, telling him to just thump away on it - again, nice, even quarter notes. For the third lesson, Dad shows him how to go back and forth: A - E - A - E*. Back and forth, nice even quarter notes. When Johnny doesn't show up for his fourth lesson, Dad calls his wife at work to see if Johnny forgot about his lesson. The wife replies, "Oh. Didn't you hear? He left this morning to tour with Garth Brooks."
