"So how do we get in?" Molly asked. "Simple. We dress as clowns." "Clowns? Bill, I hate clowns." "Everyone hates clowns. That's why nobody looks at them too closely." "And the presents?" "Stacked by the bouncy castle. We grab them during the piñata." "Why the piñata?" "Because, Molly, when forty kids are swinging a bat blindfolded, chaos reigns. Nobody notices two clowns wheeling out a wagon." "A wagon." "A red one. With balloons tied to it. Disguise it as part of the act." "You've thought about this." "I've thought of nothing else for three days." "That's deeply concerning." "The cake comes out at two. That's our window." "And if a parent stops us?" "You honk your nose and juggle. Buys us thirty seconds." "I can't juggle." "Then you'd better learn by Saturday." "Bill, this is a six-year-old's birthday party." "With premium loot. iPads, Bill. Little kids get iPads now." "That's tragic." "That's opportunity." "What if we get caught?" "We won't. But if we do, we cry. People can't arrest a crying clown." "That's the dumbest plan I've ever heard." "Is it working?" "...A little." "Grab your wig." "Fine. But I'm not wearing the giant shoes." "The shoes are non-negotiable, Molly."
