Bill said, "Molly, let's go over the plan one more time. We're breaking into that children's birthday party to steal all the presents. It's going to be our biggest score yet. You create a distraction by pretending to be the balloon animal maker while I sneak the gifts out the back door into our getaway van." "No, Bill, that's too obvious. The parents will notice a strange clown stealing toys. We should both go in as the surprise guests from the rental company. Act like we're delivering more presents but actually taking them all. During the magic show or whatever they have, the kids will be focused elsewhere," Molly replied. "You're right. We'll wear those silly hats and mingle. Then when the cake comes out, boom, we grab the pile and run. But what if the kids see us?" Bill responded. "We tell them it's part of the game, like a treasure hunt but for the adults. They'll buy it. Just don't drop any of the big boxes or the gig is up," said Molly. "Perfect. This will be hilarious. Thieves at a kids party. Who would suspect?" Bill added.
