"I am a boy, and then I explode"

One of my younger guitar students sang those ingenious words while learning the G and Em chords today. He went on to sing, "I am a boy, and then I explode. Then I go to heaven, and then I explode. I go to the bad place, and then I explode. So then I go back to heaven." I asked him how many times can you explode. His answer: "four....thousand."
