“Molly, repeat the plan.” “Enter the children’s party, locate the presents, and exit before anyone notices.” “Excellent. And the disguises?” “You’re a magician. I’m a balloon artist.” “I hate balloons.” “They hate you too, Bill. You inflate them backward.” “Where are the presents?” “Beside the cake table, beneath a sign reading DO NOT TOUCH.” “Finally, instructions written for us.” “Actually, it says, ‘Do not touch until after cake.’” “Then we steal cake first.” “We are stealing presents, not launching a pastry crime spree.” “The birthday song begins at three.” “How do we know?” “The invitation says so.” “You read the invitation?” “I forged it.” “Once inside, I distract the parents with a magic trick.” “The disappearing coin.” “You’ve lost twelve coins performing that.” “Exactly. They’ll be distracted searching.” “I’ll gather presents in my sack.” “You brought a sack?” “I brought three: one says ‘Laundry,’ one ‘Potatoes,’ and one says ‘Definitely Not Presents.’” “Take the laundry one.” “Why?” “Because no child wants to open socks.” “Bill, these are gifts, not loot.” “Then let’s call it surprise redistribution.” “Fine. But if anyone asks, we’re entertainers.” “Now hide the crowbar.” “I brought a kazoo.” “Better. Nobody suspects kazoos.” “Except the children.” “They suspect everyone.”
