A/N: Man, this was a whole lot shorter than I expected! Enjoy!

"That was a successful day," Isabella said as she and the boys took their places under the tree once again. The sun was just starting to go down, and they were expecting Phineas and Ferb to get home any moment now.

"I have to agree," Baljeet said. "We found out where Perry went, discovered an agency that does not seem to have a cool acronym, you earned another patch..."

"I really should have thought about using clay for your back-up trap, but like I said, I'm saving money!" Doffenshmirtz shoved the agent off of him, and prepared to fight back. Only to have the clay cage thrown at him from the other side of the room. "Ouch! That stuff really hurts!" Perry was about to give him another black eye when something caught his attention.

"Hey, Isabella!" Phineas greeted with a wave, as he and Ferb entered the backyard while the rest of the Flynn-Fletcher family headed inside.

"Hey, Phineas," Isabella said with a smile.

"Whatch doin'? I hope you weren't too bored with us gone."

"Not really, but it would have been more fun if you were here," Isabella answered.

"Yeah, well, our day was pretty boring..." Phineas sighed, rubbing the back of his head. He looked back at his friends. "So what'd you get up to?"

"We found out where Perry goes everyday!" Isabella said excitedly, pointing to Baljeet and Buford.

"You are not gonna believe this," Burford said, shaking his head and holding out his arms.

"I almost did not believe it," Baljeet said. "And I saw it!"

"You want to know what that is?" Doofenshmirtz asked, beaten and bruised, as Perry pointed to a cylinder on a tri-pod with wheels, and a laser-gun pointing out of it. "Oh, that's just the Forget-About-It-Inator. I rebuilt it! Y'know, just in case I need someone to forget about something." Perry perked up hearing this, and rushed over to the Inator. He angled it so it was pointing to three certain people at a certain house.

"What are you doing?" Doofenshmirtz asked. "You have something you want someone to forget about?" Perry nodded, fired the Inator, then shoved it over the edge of the balcony. Doofenshmirtz rushed over to watch it fall.

"Now why did you do that?!" he snapped, but Perry was already on his hang glider heading for home. "CURSE YOU, PERRY THE PLATYPUS!"

"So, where does he go?" Phineas asked, nudging Ferb in anticipation for having this age-old question finally answered by his friends.

"Well, he-" Isabella was cut off when a green beam hit her and Beljeet and Buford.

"I wonder what that was all about," Phineas said to his stepbrother.

"Ugh, what was I saying?" Isabella asked.

"You were about to tell us where Perry goes," Phineas reminded her.

"Perry?" Baljeet said. "We... do not... know where Perry goes." Phineas stared in shock.

"But you just said-"

"I can't remember what I was doing five minutes ago," Buford said, rubbing his head. He glanced at the other four children. "Who are you guys again?"

"As far as we're concerned," Isabella said. "It was a pretty boring day." She shrugged. "Well, I'd better get home," she added cheerfully. "See ya!"

"Yes, I too must be going," Beljeet agreed. "Good bye." Buford said nothing, but also left, leaving Phineas and Ferb alone in their yard. Phineas turned to his brother.

"You know, Ferb," he said, with a disappointed sigh. "I was really looking forward to finding out where Perry goes."

"Perhaps it was never meant for us to know," Ferb said simply. Just then, Perry walked up to the two boys, and chirped.

"Oh, there you are, Perry," Phineas said. Then he and Ferb went inside for dinner.

A/N: So, yeah, that's the story. :3 And, if you're curious as to what Phineas and Ferb got up to, then you're in luck, because - like some episodes (Unfair Science Fair/Redux) - I will post their side of the story. So, stay tuned for another update! :D
