The warehouse smelled like stale popcorn and desperation, which felt appropriate given what Molly and Bill were about to attempt. "So we just walk in dressed as clowns," Bill said, admiring his oversized shoes. "Not clowns," Molly snapped, adjusting her wig. "Mascots. There's a difference." "What difference?" "Clowns are terrifying. Mascots are beloved. We need to be beloved, Bill." Bill squeezed into a foam bear costume that smelled like someone else's regret. "I feel ridiculous." "You look like Bunsy the Birthday Bear. Very convincing." "There's a real Bunsy?" "There's always a real Bunsy." They practiced their entrance—jazz hands, a little shuffle—like two idiots auditioning for a children's show nobody asked for. "Remember," Molly said, "we grab the presents during the piñata chaos. Kids will be blind with sugar and violence. Nobody notices two mascots loading a getaway van." "And if someone asks why Bunsy's stealing presents?" "Bunsy doesn't explain himself. Bunsy just is." Bill nodded solemnly, as if this were sacred wisdom. He waddled toward the door, tripped over his own paws, and crashed into a folding table. Molly sighed, hoisting him up. "This is why we rehearse, Bill." "I thought this was rehearsal." "It was." They stepped into the sunlight, two overstuffed disasters marching toward larceny, giggling like the children they were about to rob.
