"So the plan," Bill whispered, "is we dress as clowns." "Bill. No." "Why not? Clowns are invisible at kids' parties. Nobody questions a clown." "Nobody trusts a clown either. Kids scream at clowns." "Fine. Magicians, then." "We don't know magic." "I know one trick. The disappearing quarter." "We're stealing presents, not doing a talent show." "Exactly! We do the trick, everyone's distracted, presents disappear too. Same principle." "That's not a principle, that's a coincidence with extra steps." "Do you have a better idea, Molly?" "Yes. We say we're the caterers. Walk in, load the gifts into the 'dessert cart,' walk out." "There's a dessert cart?" "There will be once we steal one." "So we're stealing a cart to steal presents." "Correction: borrowing a cart to acquire presents." "You always make theft sound like brunch." "That's why I'm in charge of the words and you're in charge of lifting things." "I lifted that safe last week." "You dropped that safe last week." "It landed safely." "On your foot." "Softly. On my foot. Softly." "Just get the balloons, Bill. We're clowns now."
