Molly spread the blueprints across the table, knocking over a juice box. "The bounce house is our entry point, Bill. We tunnel underneath." "Tunnel? Molly, it's a backyard birthday, not Fort Knox." Bill scratched his head. "Why don't we just walk in the gate?" "Because there's security," she whispered dramatically. "It's a golden retriever wearing a party hat." Molly slammed her fist down. "That dog has seen things, Bill. He knows our faces." "We've never met the dog." "Exactly what he wants you to think." She pointed at a crayon-drawn map. "The presents are stockpiled here, near the piƱata. We grab everything during pin-the-tail-on-the-donkey, when they're blindfolded." Bill leaned forward, intrigued despite himself. "Okay, that's actually clever. But how do we get past the parents?" "Simple. You'll be dressed as a clown." "Absolutely not. I have a phobia." "You're afraid of clowns?" "I'm afraid of being one!" Bill crossed his arms. "Besides, last heist you made me wear a chicken suit." "And it worked beautifully." "I got pecked by actual chickens, Molly!" She sighed, sliding him a red rubber nose. "Look, do you want little Timmy's mountain of LEGO sets or not?" Bill paused, then grabbed the nose. "Fine. But I'm keeping the Millennium Falcon."
