Bill scratched his chin. "So Molly, how exactly are we gonna pull off breaking into this children's party to steal all the presents? The place will be crawling with hyper kids and suspicious moms." "Easy Bill," Molly replied. "We arrive disguised as the pony ride operators. While the little darlings are riding, we sack up the gifts from the table. Use the bouncy castle for our getaway. It's brilliant because no one suspects the entertainment of being thieves." "But what about the birthday boy? Won't he be devastated without his presents? And if we get caught we'll never live down being the jerks who robbed a kids party," Bill said. "Bill stop worrying. Kids get presents all the time. This is our ticket to the big time. We'll be laughing about this heist for years. During musical chairs that's when we strike. I'll signal you with a sneeze and you knock over the cake as distraction. Then we grab everything and run to the van parked behind the clown's car. Trust me it's foolproof." "Okay Molly you convinced me. But next time can we steal from adults? This feels too evil. Let's go over the timing again so we don't mess up." "Deal. We hit at three when the ice cream is served. Now let's practice our pony voices."
