"Phase one, we wait for the magician's big finale," Molly whispers. "Everyone's watching the rabbit vanish, so we break in through the back window and make the presents vanish too." "And the parents?" "Busy pretending the magician's funny." "And the bouncy castle?" "Already deflated, thanks to me." Bill squints suspiciously through the window. "That rabbit's staring at me." "Rabbits don't snitch, Bill." "There's a kid guarding the gift table. He's got a walkie-talkie." "He's six." "He's wearing a lanyard that says 'Security.'" "Then we bribe him with gummy bears." "We don't have gummy bears." "Then bribe him with your dignity." Bill sighs, tugging his horn. "I'm dressed as a unicorn, Molly. I have no dignity left." "Exactly. Nobody suspects a unicorn." "Why are you carrying a crowbar in a balloon bag?" "Emergencies. Or balloons." Molly pats her balloon bag fondly. "Molly, we're robbing children." "We're redistributing wrapping paper. Gift tags are just suggestions. And we take everything." "Even the ones wrapped in newspaper?" "Especially those. Grandma always stuffs a twenty in them." "And the cake?" "Cake is a present, Bill." "And the getaway?" "The ice cream truck's parked outside." "Does the driver know?" "He will, once he sees the crowbar."
