Molly, this is the dumbest idea since we robbed that church bake sale. A children’s party? We’re stealing from toddlers now? Oh relax, Bill. They’re six-year-olds. What are they gonna do, bite your ankles? The presents are piled like a mountain under that big rainbow banner. In, grab the sacks, out. Easy. Easy? There’s a clown, Molly. I hate clowns. Last time one of those painted freaks offered me a balloon animal I nearly had a heart attack. You’re such a baby. Look, we wear the matching dinosaur costumes, blend right in. I’ll distract the parents with my award-winning “concerned mom” routine while you stuff the loot in the piñata sack. Who’s gonna suspect the T-Rex with the suspiciously lumpy tail? This is why we keep getting caught. Your plans always sound like rejected episodes of Scooby-Doo. What about the magician? That guy’s got cards and everything. We bean him with a juice box if he gets frisky. Come on, Billy-boy, think of the haul. Nintendo Switches, Barbie dreamhouses, those noisy little robots that cost more than our last score. We’ll be set for months. Fine. But if I get hit in the face with a party blower again, I’m burning the getaway van. Deal. Now help me practice my “ooh, is that a real fire truck?” face.
