"Right, so here's the plan," Molly whispered, unrolling a crayon drawing she'd stolen from a kindergartner. "We go in through the bouncy castle." "The bouncy castle," Bill repeated flatly. "The bouncy castle." "Molly, we're adults." "Allegedly." "I'm not fitting through a bouncy castle entrance dressed as a clown." "That's why you're dressed as a clown! Nobody questions a clown near a bouncy castle. It's essentially camouflage." "It's essentially humiliating." "Same thing, different outfit. Now, once you're inside, you create a distraction." "What kind of distraction?" "Make a balloon animal. Something impressive." "I don't know how to make balloon animals." "Bill, you have one job." "My one job was supposed to be getaway driver!" "That was before Gerald ate the car keys." "Who brings a dog named Gerald on a heist?" "He's emotional support." "He's a liability." "He's family. Now focus. I grab the presents, stuff them in the piƱata bag, and we walk out." "Through the bouncy castle?" "Through the bouncy castle." Bill stared at her for a very long moment. "I want a bigger cut." "You get whatever Gerald doesn't eat."
