Molly adjusted her oversized clown wig in the rearview mirror while Bill fiddled with a comically large pair of wire cutters. The van smelled like old pizza and regret. They watched a cluster of balloons bobbing above the backyard fence like colorful traitors. “We hit the presents at the piñata distraction,” Molly whispered. “I’ll be the dancing bear. You’re the grumpy dad who forgot the cake.” Bill snorted. “Last time you were the bear, you knocked over a toddler. Kid thought it was a hug.” “That was tactical. Kids love hugs. Also, I got three goodie bags and a juice box out of it.” “Focus,” he said, checking his novelty mustache in the mirror. “We grab the mountain of wrapped boxes, dump them in the inflatable dinosaur, and waddle out like it’s normal. Nobody questions a dinosaur at a kid’s party.” Molly grinned wickedly. “What if the birthday boy wants to ride it?” “Then we upgrade to a two-man dinosaur costume and charge extra for emotional trauma.” Bill sighed. “This is why we never get invited to normal crimes anymore.” “Normal crimes are boring,” Molly said, sliding her sunglasses on. “Let’s go ruin some childhoods with style.”
