Molly crouched behind the bounce castle, peering through the streamers. "Bill, there are forty kids in there. Forty. And the piƱata is guarded by a clown." "Relax," Bill whispered, adjusting his fake mustache. "The clown is my cousin Gary. He owes me forty bucks." "That's not a plan, that's a family feud." "Phase two: we wait for cake. Everyone's distracted by cake." "And phase three?" Bill pulled a sack from his jacket. It was enormous. "We grab every present with a bow on it, and nobody notices because they're too busy screaming about sugar." Molly squinted. "Bill, that's a pillowcase." "It's a heist bag. Professionals use pillowcases." Just then, a small boy in a cardboard crown toddled over. "Are you the magicians?" Molly froze. Bill smiled. "Yes, kid. We're magicians. Watch this." He reached into the bag and pulled out a rubber duck. The boy gasped in delight. "Bill," Molly hissed, "that's the duck from the gift table." "Shh. Half the job is improvisation."
