"Bill, we're really robbing a children's birthday party?" "Molly, relax. Kids are ruthless; they owe reparations." "I'm not stealing from toddlers. They pronounce spaghetti with a 'b'." "Exactly, they're drunk on juice and consonants. They won't notice a few missing presents." "A few? You said we were liberating surplus joy." "Semantics. The job is simple. We sneak in with balloon animals, sneak out with Nintendo." "And when the magician saws us in half for stealing his audience?" "Then technically we become two thieves each. Efficiency." "I cannot go to prison because you want free Lego." "Think bigger. Those parents spent mortgage money on branded plastic. We're recycling." "Into our getaway van." "Rebranded as the Community Gift Redistribution Vehicle." "Bill, there will be clowns." "Camouflage. We dress as clowns, blend in, steal everything not stapled to a crying child." "I don't do clown makeup." "You already have anxiety; that's half the look." "What's my clown name then, genius?" "Swipey McGee, Mistress of Gift Disappearance." "That's not even family-friendly." "Neither is charging twenty bucks for a paper crown and cold pizza." "Fine. One condition." "Name it." "We leave the stuffed animals." "Molly, you're killing my retirement plan." "Bill, I'm saving your soul."
