Quab: Something immature; something unfinished.
"Who would have thought the oh so great Tony Stark, Iron Man and one of the most brilliant engineers in the country, would have trouble putting together a crib from IKEA?" Pepper asks, smirking as she sits in the armchair in the nursery they'd put aside for the baby, watching Tony struggle with the wooden dowels and the instruction manual.
"To be fair," Tony points out, wiping at his brow and pushing some errant strands of dark hair away from his eyes, "it's a job for two people. Look, see." He holds up the instructions for Pepper's inspection, so she can see the two smiling people working together on the crib. She just rolls her eyes, rubs her belly pointedly, and leans back farther in the chair. It really was quite comfortable.
"I'm sure you can manage," she tells him, looking out the window at the sparkling skyscrapers of the city.
Tony glares at the instruction manual again - there was no way in hell that dowel A could fit into hole B, no goddamn way - before shrugging and turning pointedly away from the instructions, putting together parts as he saw fit.
Pepper turns back half an hour later to find that Tony has built a Gundam suit for their child. He looks extraordinarily pleased with himself, and she sighs, fighting back a smile, and tells him to take a picture. He asks why, and she tells him that the baby may not like the suit very much, and so he will have to dismantle the whole thing.
Tony pouts, but Pepper isn't swayed, so he mutters to JARVIS to save the dimensions of the crib-suit for future reference before sighing and taking it apart.
