"Okay, Bill, repeat the plan." "We sneak into Tyler's sixth birthday party, grab every present, and leave." "Wrong. We're not sneaking. We're entertainers." "I'm not wearing the clown shoes again, Molly." "You'll wear them, because nobody questions a clown carrying eleven gift bags." "Kids question clowns constantly. Last time a girl asked if I was sad inside." "Were you?" "That's not the point!" "The point is the bouncy castle. It's the perfect distraction. Once the parents start screaming, we swap the presents for identical empty boxes." "Where did you get identical empty boxes?" "I wrapped them myself. Forty minutes. There's a dinosaur theme." "Molly, this is low, even for us." "Low? Bill, there's a Lego castle in there worth two hundred dollars." Bill sighed. "Fine. What if the birthday boy catches us?" "Then we make him a balloon giraffe." "I can't make balloon giraffes." "Nobody can. That's why they'll be impressed by a lumpy snake." "And the getaway?" "Ice cream truck. Parked out front." "Whose is it?" "Ours now. Don't ask about Gary." "Who's Gary?" "Exactly. Now put on the nose, Bill."
