Molly spread the blueprint across the table, smoothing out the crayon drawings. "This is the layout?" Bill squinted. "It's a child's drawing of a unicorn." "It's the back of the layout, genius. Flip it over." He turned the paper around. "Right. So we go in through the bounce house?" "Obviously through the bounce house. Nobody suspects the bounce house." Bill scratched his chin. "What about the clown? He looked dangerous." "That clown is seventy-two years old, Bill. His name is Gerald. He has a hip replacement." "Clowns terrify me. Always have." Molly rolled her eyes. "The presents are stacked by the cake table. We grab them during pin-the-tail-on-the-donkey, when everyone's blindfolded." "Genius," Bill whispered. "But how do we carry forty gift bags?" "We bring the piƱata. Hollow it out, stuff it full, walk right out the front door." "Won't they hit it with a stick?" She paused. "That's a fair point, actually." "See? I think things through." "Fine. We use the magician's disappearing box instead. Saw it in half, fill both halves with loot." Bill grinned, finally satisfied. "I love it when a plan comes together." "It's not together yet. You're wearing the bunny costume." "Absolutely not." "It's already decided, Bill."
