Most kids’ rhymes and jump rope songs are sick & twisted too. Mary Borden took an axe, gave her father 40 whacks... Ring around the Rosie, pocket full of posies, ashes, ashes, we all fall down (dead). Etc.
Rock-a-bye baby in the treetop... When the wind blows the cradle will rock; If the bough breaks, the cradle will FALL! And down will come baby... ? CRADLE AND ALL! DA FUQ?
