Disclaimer: Nope, I don't own Trigun, or babies, or hot dogs.

Legato sat alone on his cliff. He bent over the mechanism in his hands with the deepest concentration. His eyes burned with obsessive determination. "Red, blue, yellow, blue, green, blue-- No!" He leapt to his feet with distress. "I keep hitting blue! I must be a Simon master!" He threw the game off of the cliff and watched it shatter on the rocks below. Pouting silently he sat back down and let his feet fall of the ledge and swung them discontentedly. His golden eyes fixed on the double-sunlit sky.
Suddenly, it hit him. A pressing question; one that had to be answered. It was age-old, yet still...
He ran, well, as well as a sophisticated evil-type character can run in a trench coat enforced with metal, towards the town that his conveniently placed cliff overlooked. He wandered through the streets until he came upon the Thompson girl. She was in the process of consuming a rather frighteningly large quantity of pudding. He strode up to her. "Milly, I have a question!"
"Um, no, you can't have any pudding."
"No no no. Not that question. Where do babies come from?"
Milly tipped her head to one side and ate another pudding. "Actually, I don't know." She blinked a few times. "But I'll bet somebody else knows. Let's go ask!"
So off they went.
They next happened upon Meryl sitting at her typewriter. She didn't even look up as they approached.
"Meryl, where do babies come from?"
Meryl fell off the chair and smudged her fingers across the keys, causing a jumble of random letters to appear on the report. She looked up slowly.
"That's not something I wish to tell you. Go ask someone else. AND KNOCK NEXT TIME!!!"
The quest continued.
They found Wolfwood playing ball with some children in the main park. Milly ran up and tugged on his arm. "Mr. Priest, where do babies come from?" The children snickered quietly. Wolfwood looked at the insurance agent and the psycho, I mean psychic oddly. "Uh, why do you want to know?" Milly, totally oblivious as usual just smiled. "Legato asked me and I didn't know."
Wiping a hand across his brow in relief the priest smiled. "Oh, okay then. Well, babies--" The children giggled. Wolfwood paused and thought about what he had just done. "Why don't you ask someone else?"
Still answer less they headed off.
Knives was a lot less helpful. Legato rushed forward and bowed before asking the accursed question. "Master, where do babies come from?" Knives sat back thoughtfully. Then he shrugged and grinned broadly. "I dunno, but they taste good! Oh, and Legato, remember it's your turn to cook dinner tonight. Pick up some red wine at the store. I'm all out."
Our poor knowledge seekers were becoming quite tired by now. At last they saw Vash in a local doughnut shop. "Vash-san, Where do babies come from?" They chimed in symphony. He picked up his doughnuts and smiled. "What?"
"Where do babies come from?!"
Milly found it interesting that Vash's face could match his trench coat in hue. This was a new fact.
Looking contemplative his sat down on a park bench and started munching on the defenseless doughnuts. The settled at his feet, much like small children to a storyteller.
"Well, the stork brings them, of course!"
Sudden understanding flooded Milly and Legato's faces. "Ohhhh... of course! Thank you!"
waving at Vash they made their way back to Milly's now empty bag of containers. Kuro Neko-Sama sat beside it, licking pudding of off his paws. "Darn!" Milly moved the obstructing feline and sat down. Joining her on the other side of the bench Legato pulled out a large bag and produced several hot dogs. They sat eating in silence for several moments before Legato looked down at the sausage in his hand.
"...What are in hot dogs?"
