"Tell me again why we're robbing a children's party, Bill." "Market research, Molly. Kids are the only demographic that still believes in unmarked cash envelopes." "They’re six. They believe in unicorns and broccoli that tastes like pizza." "Exactly. Their defenses are down. Plus, birthday wrapping: nature’s camouflage." "Walk me through the plan before my conscience wakes up." "Phase One: infiltrate as entertainment. You juggle, I perform close-up magic." "You can’t juggle and your last magic trick set the couch on fire." "Details. I’ll juggle the fire this time; it’s called growth." "And the presents?" "Phase Two: while I distract with my tragic skills, you slip the gifts into this eco-friendly, morally-questionable sack." "That sack says ‘Laundry – Do Not Steal.’ Subtle." "It’s reverse psychology." "It’s mildew." "Focus. Phase Three: exit strategy. We lead the kids in a conga line, right out to the van." "Bold. Kidnapping adjacent." "They’ll think it’s a field trip. To the Parking Lot of Dreams." "And if the parents catch us?" "I cry, you blame budget cuts to the arts." "Somehow society is still at fault." "Look, Molly, are you in or out?" "I’m in. But I’m stealing the cake too." "Fine, but we leave balloons."
