Molly adjusted her oversized clown wig and squinted at the colorful invitation. “Bill, this is the dumbest idea you’ve ever had, and that’s saying something. We’re robbing a children’s party?” Bill grinned, waving a handful of balloons. “Exactly! Think about it, Moll. Twenty screaming kids, zero security, and a mountain of wrapped presents stacked like a shiny pyramid. We hit it during musical chairs, grab the loot, and vanish before the cake’s even cut.” “We’re going to hell for this,” Molly muttered, checking her fake mustache in the mirror. “I’m dressed as a children’s entertainer. If my mother could see me…” “Your mother thought knocking over the post office was a phase,” Bill said. “This is high art. We blend in, Moll. I’ll do magic tricks, you juggle. Then we stuff the van with enough Barbies and Nerf guns to retire to Florida.” “What if some kid starts crying?” she asked. “We give him a balloon animal and tell him Santa sent us. Simple.” Molly sighed. “If we get caught I’m blaming you. And I’m keeping the giant stuffed unicorn.” “Deal,” Bill said, high-fiving her. “Now let’s go ruin some birthdays.”
