Molly cracked her knuckles and grinned at Bill. "So we're really doing this? Stealing from a kid's birthday party?" "Not just any party. The Vanderbilt kid. That brat probably got a pony wrapped up in there." "How do we even get in?" "Easy. I dress as a clown, you're the face painter." "I'm not painting faces, Bill." "Fine, you be the clown." "I'm not being a clown either!" "Well somebody's gotta be the clown, Molly!" "Why does anyone need to be a clown?" "Because it's a children's party! We need to blend in!" "Right, and nothing says 'blend in' like a six-foot clown and a face painter who refuses to paint faces." "You got a better plan?" "We could just walk in. Say we're with the catering company." "Oh sure, and when they ask where our trays are?" "We say we're on break." "That's your genius plan?" "Better than your clown idea." "My clown idea is classic!" "Your clown idea is getting us arrested." "Fine. We'll go with boring." "Good." "But I'm still bringing the nose."
