Molly leaned over the crumpled party invite, grinning like a fox in a henhouse. "Bill, it's perfect. Little Timmy's bash—fifty screaming rugrats, mountain of presents under that balloon arch." Bill wiped sweat from his brow. "Presents? Molly, those are mostly Barbies and Legos. What's the fence gonna say? 'Stolen slime kits'?" "Slime sells, you lug! We crash as the magician and his assistant. I do the disappearing act on the gift table while you distract with card tricks." "Card tricks? Last time you sawed me in half, I limped for a week! What about the parents? And the birthday boy? He'll wail like a siren." Molly cackled. "We spike the punch with sleepy-time juice—non-lethal, promise. Kids chase the piñata, boom, we scoop and scoot in the bounce house truck." Bill gulped. "Bounce house? I'm sixty-two! One wrong bounce and I'm pancakes. And if a toddler rats us out? 'Mommy, the clown stole my Fortnite skins!'" "Relax, we'll wear those creepy mascot suits—nobody questions Elmo. In, out in ten. Richest haul since the Easter Bunny heist." Bill sighed. "Fine. But if I get glitter-bombed, you're waxing the van." "Deal. Tomorrow, we gift-wrap crime!"
