"Bill, listen up. We break into that children's party right when they blow out the candles. That's our window of opportunity," Molly said. "Window? Molly, this is a kiddie bash not Fort Knox. What are we gonna do, steal the pin the tail on the donkey game?" Bill said. "No, the presents, all of them. Those boxes are loaded with the latest gadgets and toys that we can fence for good money. It's brilliant because no one expects thieves at a birthday party," Molly said. "True, but how do we blend in? I don't want to wear a silly costume," Bill said. "We go as clowns, obviously. You'll distract the kids with balloon animals while I bag up the gifts under the table. Then we make our getaway in the ice cream truck we stole last week," Molly said. "But the parents? And what if the birthday kid cries?" Bill said. "Parents will be busy with cake, and one fake present swap will do the trick. We'll leave them a bag of rocks wrapped nice. They'll be none the wiser," Molly said. "Okay, you're the boss. But if we get caught it's your fault. Stealing from kids feels low even for us," Bill said.
