In a smoky hideout, the two thieves discussed their bold plan. "Bill, ready to break into the children's party and steal all the presents?" "Ready, Molly, but it's a terrible idea. The kids will be so disappointed." "Disappointed but we'll be rich, Bill. You juggle to distract them while I take the presents out the back. No one will notice in all the chaos. It's brilliant." "Brilliant? It's desperate but I'm in. What's our cover story?" "We're the hired entertainers. You're the magician. We strike after they sing happy birthday. That's our window." "Will we wear costumes? I hate the clown suit." "Yes, the clown suit is essential to hide our faces. We'll fill the room with balloons for chaos then snatch the presents and getaway. This heist will make us legends." "Legends or jailbirds. I'm in but we skip the favorite gift. I have some morals." "Deal. No favorite gifts. Let's memorize the address and get ready. The party starts soon." "What if the clown gets us caught? Last time it was a disaster." "Don't worry about that. This time we'll succeed. Just remember to smile and act fun for the kids before we rob them blind."
