Molly pressed her binoculars to her face and peered through the hedge at the backyard full of balloons and screaming kids. "Okay Bill there are at least twenty presents on that table and a clown guarding them," she whispered. Bill adjusted his fake mustache which was already falling off in the heat. "A clown? You told me it would be easy. I hate clowns. They stare into your soul," he hissed. Molly lowered the binoculars and grinned at him like this was the best part of the plan. "Relax. Clowns scare easily. We just wait for the cake, then you create a distraction while I grab the loot," she said. Bill fanned himself with a stolen party invitation and stared at the bouncy castle with deep suspicion. "Why do I have to be the distraction? Last time I was the distraction I ended up in a pinata," he whined. Molly patted his shoulder and pulled two water pistols out of her tote bag. "Because you are big and loud and kids love chasing big loud idiots. I am small and sneaky and excellent at stealing," she explained. "Great. So my talent is getting tackled by seven year olds hopped up on frosting. I should put that on my resume," he muttered. A chorus of happy birthday erupted from the yard as a woman carried out a giant chocolate cake. "That is our cue. Remember, you run in screaming about the ice cream truck, then I slide under the gift table," she said quickly. "What if there is no ice cream truck? What if they see through my mustache? This feels morally wrong even for us," he said nervously. Molly rolled her eyes and stuck a party hat on his head. "Bill, we once stole a wedding cake during the vows. This is a bunch of six year olds. Get your game face on," she ordered. "Listen, there are race cars, dolls, and gift cards in those bags. We could retire early if we pull this off without getting glitter bombed. Do you understand me now?" Bill sighed and fixed his mustache. "I understand that I am risking my dignity for a bunch of slime kits and juice boxes. But fine, if the clown charges me I am throwing this mustache as a decoy. I swear it." "Good. Once I have the presents, meet me by the fence with the van running. No honking, no singing, and absolutely no eating the candy until later. Is that clear?" Molly grinned and loaded her pistol. "Crystal clear, boss. But if a kid asks me to make balloon animals, I am doing it. I have a reputation to protect and my giraffe is fantastic. You cannot rush true artistic greatness okay?" "Focus Bill! This is the biggest birthday score in the neighborhood. Steal the gifts, dodge the clown, outrun the sugar crazed toddlers, and we will be legends of terrible decisions forever. Now go be brave. Go now." They bumped fists behind the hedge.
