Molly adjusted her fake mustache. "The Henderson kid's birthday party is Saturday. Fifty presents under that tree." "We're stealing from children?" Bill whispered. "Rich children. Their parents won't even notice." "Molly, this is insane. Remember when you stole those commemorative spoons?" "We don't talk about the spoons." "I'm just saying, maybe we should target someone our own size." "The presents are wrapped in gold paper, Bill. Gold. One of them has to be expensive." "Or it's socks. Kids get socks wrapped in gold paper." "Not these kids. Trust me." "Your last plan involved a llama and a fire extinguisher." "That worked perfectly!" "The llama broke your arm." "Minor setback. Look, we dress as clowns, blend in, and grab the gifts during the chaos of the piƱata." "We're going to jail. We'll be on the news." "'Local idiots arrested at children's party'?" "Exactly!" "Bill, we've robbed banks. We rappelled off the Chrysler Building." "And yet here we are, planning to steal toy trucks." "They might be real trucks." "They're toy trucks, Molly."
