"So we just walk in?" Bill asked. "We walk in," Molly confirmed. "Dressed as clowns." "Dressed as clowns." "Molly, I hate clowns." "Everyone hates clowns. That's the point. Nobody looks too closely at a clown." "And the presents?" "Big sack. Clowns carry big sacks." "That's Santa." "Santa, clowns, same energy." "It is absolutely not the same energy." "Bill, focus. We grab the gifts, we honk a few horns, we waddle out the back." "What if a kid cries?" "Kids always cry. That's just ambiance." "And the parents?" "Distracted. Cake, juice, existential dread. They won't even notice." "What about the magician they hired?" "What magician?" "There's always a magician, Molly." "Then we steal his rabbit too. Bonus." "You want me to pickpocket a magician." "I want you to commit, Bill." "This is the worst plan you've ever had." "Worse than the petting zoo?" "...Nothing's worse than the petting zoo." "Exactly. So we're improving." "My eyebrows still haven't grown back." "Llamas hold grudges. Lesson learned. Now grab your wig." "It smells like sadness and balloons." "That's the smell of money, Bill." "It's the smell of regret." "Same energy." "Stop saying that!" "Put the nose on. We've got a party to ruin."
