Molly Jenkins leaned over the fence staring at the bouncing castle and presents. "Molly, this is low, even for us." "Low? There's a mountain of free toys right there and no security." "That mountain belongs to a five-year-old named Timmy who has a dinosaur cake." "Perfect, Timmy doesn't need a Nintendo Switch, we do, it's called income redistribution." "We will get destroyed by parents and a very angry clown." "No, you will distract the clown with balloon animals while I grab the loot." "Oh excellent, so I get murdered by a clown while you become the birthday Grinch?" "Exactly, you have such a natural way with children and law enforcement." "I have a natural fear of being tackled by seven-year-olds hopped up on cake." "Relax, it's operation Piñata Payday, it's foolproof, nobody suspects the adults." "You named our felony operation Piñata Payday?" "Focus, here comes the mom with the juice boxes, just act totally normal." "I am acting normal, I'm normally terrified of stealing from toddlers, Molly." "How many juice boxes until you feel morally okay?" "Zero, I passed morally okay five birthdays ago, just follow my lead." "Fine, but I get the dinosaur cake." "Deal, you distract, I steal."
