Daughter: "Ah its so hot in the sun!!" (Before she could ask me why its hot in the sun I asked it to her) Me: "Why is it hot in the sun?" Daughter: "Because the sun is hot" Me: "Why?" Daughter: "They boiled the sun and so its hot" Me: "Who boiled it ?" (And here comes the best part) Daughter: "The planets boiled it.
