And so I enter the world of Phineas and Ferb FanFiction.
Here we go. This first half-"episode" is an idea I got when my family and I were on an adventure in Washington D.C.
… It's a long story.
It's a story about how Phineas and Ferb saved the Unites States from a horrible catastrophe. Also, it's a story of how a certain semi-aquatic, egg-laying mammal of action almost failed at thwarting his nemesis.
I own no one (except Jordan Leger, the fictional leader of the CIA in this "episode").
More details about the second half of the episode later.
Phineas and Ferb: A Capitol Mission/ Phineas and Ferb and the Pirates of the Ghost Spark

Prologue: The only ones who can help.

Omnitient POV; CIA Headquarters.

CIA agents were running frantically. This was the worst situation of their career.

Their leader, a man by the name of Jordan Leger, tried frantically to keep order.

"Listen, y'all! We've got to keep calm and find a profitable solution."

The only sound that met him was more screaming.

"ALRIGHT! I'VE HAD IT! EVERYONE QUIET!"

Everyone was silent.

"Now, let's assess the situation. And let's most certainly NOT panic."

This was what he did best. "Now, Agent Bob, read the protocols for this situation."

Bob snapped, then saying, "Okay!" Jordan sighed. Even marriage did not mellow him. "Well, I would, but we have no protocols for a massive asteroid strike on the entire United States."

Jordan started to panic.

"Alright; What we need here is a simple, inventive solution. What we need here is an inventor, who works fast!" Jordan turned to a tech agent. "Search the internet!"

"Basic search turned up only one response. It's a website put up by a self-proclaimed stalker named Irving. He basically follows two people and their friends. They say their names are… Phineas Flynn and Ferb Fletcher."

Bob then said, "Hey, I know them. They're in my family."

"Then perhaps you should call them."

He snapped again, and said, "Okay!" Jordan facepalmed, and said, "Just call them already!"

Bob started dialing, and Jordan said, "Hurry. They're the only ones who can help."

Onmitient POV; Phineas and Ferb's Backyard.

"I wonder what we're going to do today, Ferb." Phineas said to his stepbrother.

"Well, it had better be interesting." Ferb said, a rare occurrence. "We haven't had as much action since we were the Beak."

"Well, let's rebuild it. We have the blueprints; it would only take a few minutes. Ferb, I know what we-"

"Boys, I need you to come inside right now." Phineas couldn't believe he was cut off, but that could be saved for later. "What is it, mom?" I asked, as Ferb and I ran inside. "The Head of the CIA is on the phone, and he says you're these amazing inventors who can build things in less than a day. Is he right?"

"Well, yes…" I answered, nervously.

Mom just stared at us in shock. "You mean… Candace was right all along?"

"Well, yes, but…"

"That's amazing! I can't believe it! But… You never got our permission to build anything! You guys put yourselves in danger almost every Day! How could you? I don't know what to do now! You guys are so Busted!"

Candace woke up a few seconds later, saying, "Did someone say, 'busted'?"

"I just don't know what to do, now that I know you've been doing amazing things, yet putting yourself in danger almost every day…" Mom trailed off, starting to sob.

"Mom, could you hand us the phone while you try to sort your emotions out?" Ferb said. He was talkative today.

Mom nodded, and handed us the phone, tears starting to flow freely from her eyes.

"Is this Phineas Flynn and Ferb Fletcher?" I heard a voice say from the telephone. "Yes. Yes it is." I said. "Excellent." The voice said. "We need your help to save the United States."

So it was a bit short… it was a prologue; deal with it.
I'm thinking the second half of this episode is going to be a sequel to "P&F and the Temple of Juatchadoon." It should be interesting, to say the least. And so I'm reordering the Indiana Jones movies. I don't care! I'm the one writing this! Hahahahahahahahahahahahahaha haha! Okay, I'm done. Anyways, Be sure to Carpe some Diem while I'm writing the next chapter for this half of the episode.
