A/N: Well, guess who's gotten into the Christmas spirit early! Merry Christmas everyone!
"Okay, everyone ready?" Phineas said, grinning from ear to ear.
Isabella, Buford, and Baljeet nodded enthusiastically.
Ferb raised his hand.
"Yes, Ferb?"
"The step ladder is nowhere to be found."
Phineas' smile shrunk by a few notches as he considered this. "Ah, well. We'll just have to get along without it. Any other problems?"
Silence.
"Excellent!" Phineas' smile returned to its normal size. "Let's get started."
Buford began hanging the stockings while Baljeet fruitlessly attempted to light a fire, at least until Ferb showed up with a flamethrower, pausing only to toss a box full of decorations to Phineas. Isabella grabbed the Christmas lights and slung it towards the tree like a lasso, sending it spinning with a flick of her wrist just in time for Phineas to launch the ornaments at the tree. Isabella began to move on to the next project when Phineas held up the star.
"Give me a boost? It wouldn't be complete without this."
Isabella smiled and shook her head, allowing him to climb on her shoulders so he could place the star on top of the now-still tree.
"Thanks, Isabella!" Phineas said, jumping down and running off to a box and taking out a menorah, placing it carefully on a table and lighting the candles.
"Phineas, what are you doing?" Isabella asked, halting in her attempts to hang the mistletoe to ask about the obviously Jewish decoration. "You aren't Jewish."
"No," came the reply, "But you are."
Allowing herself a small, content smile, Isabella turned her attention back to her task.
"You need help?" he said, noticing her attempts to reach the hook the mistletoe was to go on above the doorway connecting the living room and dining room were coming about eight inches short.
"Yeah. Give me a boost?" came her exasperated, slightly sheepish reply.
"Sure. After all, I owe you one," Phineas said, grinning cheekily before letting himself be used as a human step ladder.
"There, perfect," the triangle-headed boy proclaimed, letting Isabella down off his shoulders and admiring their handiwork. He turned to meet the silent laughter and slightly pitying expressions of Ferb, Buford, and Baljeet.
"What?" Phineas raised a questioning eyebrow.
Ferb, shaking with barely suppressed laughter, pointed upward at a space just above Phineas and Isabella's heads.
"Wha-" The pair followed Ferb's finger, the situation dawning on them. There, hanging in the doorway between Phineas and Isabella, was the mistletoe.
Unsure what to do, Phineas leaned forward cautiously and pecked Isabella on the cheek. Just as he was about to turn away, he felt Isabella grab the collar of his t-shirt and mash her lips against his in a kiss that somehow generated more heat than the fire and his face combined.
"There," she said, pulling away from him after what felt like an eternity. "Consider your Paris debt paid in full."
Phineas wasn't sure what he said, but he suspected it was somewhere along the lines of 'meep'.
