A/N: Hi! I don't normally like fanfiction about the gang in school or as teenagers, but I was reading Trice by Whythis, and he/she inspired me to do this! I will be including an OC that is not so original. Her name is Irene, and she is based (loosely) off of Irving. The difference is that she is popular, pretty, and, rather than geeking out over the boys, Irene is interested in only Phineas. Sorry if the characters are a little OOC. Now, onto the story!

"It's a good thing Miss Stella chose us to be partners, Phinny," said Irene, playing with her long blonde hair.

"Chose us?" replied Phineas. "When she told us it was time to pick partners, you ran towards me like a crazed rhinoceros."

"Anything you say, Phinny," Irene said dreamily.

"Please stop calling me Phinny," Phineas said, his voice a little tight, betraying his mild irritation.

"Isabella called you Phinny yesterday in art class and you didn't mind," she said fluttering her eyelashes innocently.

"Yes. Mostly because she's my friend," he replied, his voice now noticeably laced with anger. Glancing at his sheet (Miss Stella was the German teacher, and the assignment was supposed to be interviewing your partner auf Deutsch) Phineas said, "Was isst du für Mittagessen?"

"What?" Irene said, looking at him as if he'd just turned into a toad.

"Was isst du für Mittagessen?" he repeated. Noticing her confusion, Phineas translated for her, "What did you eat for lunch?'

"Why does it matter?" she replied, more confused than ever.

Phineas sighed. This was going to be a long class period.

Lunch

"…and I'm pretty sure she was flirting with me!" finished Phineas.

Baljeet glared at him. "You've got one of the most popular girls in the school after you, and you're complaining?"

"Well, yeah," Phineas replied. "She's like Irving, only more suffocating and harder to shake."

Everyone at the table shuddered.

"What're you going to do about her, Phineas?" asked Isabella. They had a free period together and their teacher had decided to go down to the park, his exact words being: 'no sense staying in on a day like this'. This was perfectly fine with Isabella, because it meant some private time with Phineas (none of their other friends were in the study hall).

Phineas directed Isabella's attention towards a certain obnoxious blond. "We'll lose her in the butterfly garden, and then we can come up with a plan."

The two found a bench after shaking, at least temporarily, Irene.

"So," said Phineas, "you have any ideas?"

"Well," said Isabella, "you could pretend to date someone else. That would mean serious competition for your heart, and that would scare off most girls like Irene."

"That's not a bad idea Isabella," the redhead said. "But where would I find someone willing to do that? Irene will simply call my bluff unless she sees hard evidence."

"Phineas…" Isabella sighed, exasperated. She was just going to have to walk him through this.

"Phinny! Come out, come out wherever you are!"

"It's Irene!" Phineas said, panic flooding him. Desperate, he did the only thing his adrenaline-ridden mind could think of: he kissed Isabella.

"Oh, Phinn-" Irene rounded the corner, her face contorting in disgust as she saw the couple on the bench. The blond left, retching loudly.

"Oh, thank goodness, she's gone," said Phineas, pulling out of the kiss.

"Yeah," said Isabella dreamily, her mind having been sent more or less permanently to Phineasland.

"Isabella?" asked Phineas, "Are you okay?"

The redhead on the screen sat on the bench, waiting patiently for Isabella to snap out of it, while the one watching blushed furiously.

"Irving," said Ferb, "For once, I actually appreciate your network of spy cameras. Without them, we would never have known about this."

"You're welcome," replied Irving.

Ferb turned to the two blushing teens on the couch. Smiling to himself, he reminded himself to thank his cousin, Irene. That was one of the best performances he'd ever seen.

A/N: Sorry if my German's terrible. Well, what did you think? It's nice and long; one and a half pages on Word!
