"The clown," Molly said. "That's the weak point." "Clowns are never the weak point. Clowns are the strongest point. Clowns have knives in their little cars." "Bill." "I'm just saying I've met clowns." "The clown arrives at two. We arrive at one-fifty. We are the clown." "Both of us? One clown, two men?" "You're the balloon assistant." "There's no such thing as a balloon assistant." "Nobody at a seven-year-old's birthday party knows the industry standard for balloon assistants, Bill." "Somebody's mother will. Somebody's mother always knows." "Then you distract her." "With what?" "Balloons." "I can't do balloons. My hands sweat. They pop." "Then do a sad face and say the balloons were stolen. Mothers love a tragedy." "And the presents?" "Pile by the window, always. Every party, always the window, always unguarded, because nobody in this country believes anyone would rob a child." "Because it's despicable." "Because it's easy." "Both, Molly. It can be both." "Sixty presents. Average value, thirty quid." "That's eighteen hundred." "That's a holiday." "That's a jail sentence with a very specific description." "Bring the sack." "We're stealing from a child." "We're stealing from a child's *aunts*, Bill. Aunts buy rubbish. We're doing him a kindness." "...What's my clown name?" "Sweaty." "Right. Fine."
