"Bill, we need to talk about this children's party heist. How exactly are we going to steal all those presents without getting caught by a horde of sugar high kids?" said Molly. "We'll go in as professional party entertainers, Molly. I'll be the clown with the giant shoes and you can be the face painter. While I'm making balloon giraffes the kids will be lined up and the presents will be ripe for the picking. We grab them during musical chairs," said Bill. "That could work but what if someone recognizes us from our last job at the circus? And are we really stooping to stealing from children?" said Molly. "Come on it's not stealing it's redistributing the wealth of toys. Those kids have too many and we have none. Plus we'll leave a note saying from Santa early. The escape is easy we'll use the trampoline in the backyard to bounce right over the fence to our waiting van," said Bill. "You're insane but I love it. Let's do it. Just promise me no one gets hit with a party favor," said Molly. "I promise Molly. This will be the funniest heist in history," said Bill.
