Puff the Magic Dragon

"Puff the Magic Dragon is a song about a dragon who loves a little boy. But little boys grow into men, and grown men don't believe in dragons so they can't be friends any more. This makes Puff very sad, because dragons live forever and he's going to spend a long time missing his friend. But his friend brings his little boy, who will be his new friend. So see, it actually turns out OK."
