“Molly, why are we whispering? It’s a bouncy castle, not Fort Knox.” “Because, Bill, the parents are still inside.” “Fine. What’s the plan?” “You distract the clown.” “I hate clowns.” “You’re dressed as a magician.” “I hate magic too. Especially mine.” “You’ll make balloons disappear.” “How?” “Sit on them.” “And while I’m sacrificing my dignity?” “I slip through the kitchen, locate the gift table, and load everything into the pram.” “The pram with the fake baby?” “His name is Trevor.” “Trevor is a cabbage in a bonnet.” “Trevor has convincing cheeks.” “What about the dog?” “Bribe him.” “With what?” “Mini sausages.” “Those are for children.” “Exactly. He’ll never suspect.” “Suppose a child spots you?” “I’ll say I’m the Present Fairy.” “Do fairies wear balaclavas?” “Only practical ones.” “And if the clown recognizes me?” “Tell him you’re his replacement.” “I don’t know any clown tricks.” “You can juggle.” “Three oranges, badly.” “Perfect. Children love failure.” “Why are there so many presents?” “Birthday twins.” “Two birthdays? That’s criminal.” “Focus, Bill.” “Right. I distract, you steal, Trevor supervises.” “Then we exit through the garden gate.” “Past the pony?” “Don’t make eye contact.” “Why?” “Last time, it knew.”
