"– and then subtract seven billion for P, the world's population, add the (r) rate of childbirth, multiply by seven C for the seven continents, and you get..." Phineas blinked back into reality. "Ferb?"

His British companion turned an inquisitive look towards him. "Yes?"

"No, I really mean that's the answer! You're the answer!"

"How am I the answer to how many people can be moved to the moon?"

"I don't know." Phineas grinned. "You just happen to be the answer."

As they were young geniuses, it only took Ferb a short moment to realize what Phineas meant. "65,182… it seems like an awfully small number."

"Meh. The ecosystem is still developing, it won't be able to support much life as of yet. Now if we want to find that out, we'd have to make an equation for how quick an ecosystem can develop!"

"… Do you want to?"

The redhead thought about it honestly. "No, not really. It's a beautiful day outside, what are we doing wasting it away in here?"

"Quite."

"I know what we can do! Let's walk a dog!"

"But we don't own a dog."

"Let's make a dog and then walk it!"

Ferb considered the notion of it while Phineas stared excitedly at him. His younger step-brother was clenching his fists and his large blue eyes widened minutely for every second that ticked by. "Fine then."

"Sweet!"

Author's Note: Just something small and nonsensical. 6=F, 5=E, 18=R, and 2=B, hence 65,182.

Funny story, my nephew got me into this show! Heh heh, It's just so cute…
