Setting: At the grocery store, with the four year old in the cart (also one of the more bizarre answers you can get at the game of Clue).
Kid: I'm a new boy.
Me: Do you want olives, new boy?
Me: So what makes you new?
Kid: I've never been to Earth before. This is my first time.
Me: Do you want regular Goldfish or parmesan Goldfish, tiny Oshkosh-clad extraterrestrial?
Kid: Regular. I'm from Saturn. I'm here for work. I'm going home in three days.
Me: What's your home like?
Kid: It's painted green, and there are no baby things in my room, and my parents are like you. They have the same hair as you.
Me: How do you get back and forth?
Kid: I fly through space. In a giant bar of soap.
Me: 'Cause it's biodegradable?
Kid: Yes. Can I get a new one here?
Me: A new soap rocket? Maybe in sporting goods.
Kid: I like it here. I like meeting people. And eating olives. But I can't wait to go back to my home country.
Me: Planet. Saturn's a planet.
