Molly hunched over the diner booth table, blueprints of "Little Timmy's Birthday Bash Palace" spread out like a treasure map. Bill slurped his coffee, eyes gleaming. "Bill, it's genius," Molly whispered. "Hundred screaming rugrats, piñata stuffed with cash gifts. We crash as party entertainers—me the magician, you the clown." Bill snorted. "Clown? I'd look like a deranged balloon animal. What if the kids mob me?" "Perfect distraction!" Molly grinned. "You juggle pies in their faces while I sleight-of-hand the present pile into duffel bags under the bounce house." "But the parents? Those soccer moms with wine boxes?" "Punch bowl's our alibi. Spike it with 'magic potion'—sleepy-time juice. Harmless, just drowsy." Bill leaned in. "Entry: bounce house unzip from inside? Or piñata drop-line from the chandelier?" "Chandelier! Candy explosion covers our grab. Out the back via cake delivery van." "Van's gold—'Happy Birthday from Uncle Thief!'" Molly high-fived him. "At midnight, we're rich. Kids cry, we laugh to the bank." Bill chuckled. "Best heist ever. No alarms, just tears and frosting." "Deal sealed. Costumes tomorrow?" "Deal. But if I get glitter in my crack, you're waxing it out."
