Molly leaned over the blueprint of the McAllister backyard, tapping a finger on the little square labeled "GIFT TABLE." "So we go in through the bounce house," she said. Bill blinked. "The bounce house." "It's inflatable, Bill. Structurally weak. We slit the side, crawl through, nobody notices two adults tumbling out of a bounce house at a seven-year-old's birthday party." "Molly, everyone will notice two adults tumbling out of a bounce house." "Not if we're wearing the costumes." She unzipped a duffel bag and pulled out two enormous foam dinosaur suits. Bill stared at them like they'd personally insulted his mother. "I'm not wearing that." "You'd rather wear the clown one?" "There's a clown one?" "There was. I traded it for a smoke machine." "Why do we need a smoke machine to steal birthday presents?" "Dramatic exit, Bill. Presentation matters." He sighed, already stepping into the dinosaur suit. "We're stealing Nerf guns and Legos from six-year-olds." "Seven-year-olds," Molly corrected. "And we're professionals. Professionals commit to the bit." "The bit is armed robbery." "The bit," she said, zipping up her own tail, "is *theater*." He groaned, but grabbed the smoke machine anyway.
