“Molly, tell me again why we’re robbing a children’s party.” “Because, Bill, children receive an alarming volume of loot and guard it with the strategic discipline of wet bread.” “That feels morally squishy.” “We’re not stealing innocence, Bill. We’re stealing unopened board games, duplicate plush giraffes, and at least one remote-control dinosaur.” “What if the children see us?” “Then we say we’re from the Department of Surprise Redistribution.” “That is not a department.” “Neither is your mustache, yet there it sits, claiming authority.” “Fine. What’s the plan?” “Back gate at two. Clown arrives at one-thirty, maximum confusion window at cake.” “I hate clowns. They’re like mimes with a budget.” “You distract the magician.” “How?” “Ask him to explain his emotional journey.” “And you?” “I sweep the gift table, load the sacks, and exit through the bouncy castle.” “The bouncy castle?” “No footprints, Bill. Only shame.” “What about the dog?” “Bribe him with sausage rolls.” “What if there are parents?” “There are always parents. That’s why we wear reflective vests and carry clipboards.” “Clipboards make me nervous.” “Clipboards make everyone obedient.” “What if the birthday child cries?” “Then we leave the chemistry set. I’m a thief, not a monster.” “You’re sure about this?” “Bill, tonight we ride into destiny on a wave of ribbon and poor supervision.”
