Molly adjusted her fake clown nose and grinned at Bill. “Okay, so we hit the party at peak piñata time. All the kiddies distracted, presents piled like a shiny treasure hoard.” Bill scratched his head. “You want us to rob a children’s birthday party? That’s low, even for us.” “Low? It’s genius,” Molly shot back. “Who suspects the guy in the mascot suit? You wear the giant teddy bear costume, I’ll be the balloon lady. We’ll blend right in.” “I’m not wearing the bear suit. Last time I sweated so much I thought I’d drown.” “Fine, then you juggle. I’ll do the bear. Just don’t drop the cake this time.” Bill groaned. “We grab the gifts, run for the van, and disappear before they sing ‘Happy Birthday.’ What if some kid sees us?” Molly waved a hand. “We give the birthday boy a whoopee cushion as a decoy. He’ll be thrilled. Everyone wins. Except the parents.” “You’re evil.” “I’m efficient. Now, repeat the plan, teddy.” Bill sighed. “I create a diversion with balloon animals, you stuff the presents in the oversized diaper bag, we meet at the bounce house exit. No autographs.” “Perfect. Let’s go make some tiny millionaires cry.”
