Molly and Bill reviewed their plan in hushed tones. "So Bill, we're really doing this? Crashing a children's birthday party to steal all the presents?" Molly asked. "Yes Molly, it's genius. No one suspects the guy in the clown suit. I'll entertain with jokes while you grab the goods from the gift table. Just avoid the bouncy castle or we'll never get out," Bill replied. "But what if the kids see us? They might think it's a magic trick and cheer. Or they'll cry and we'll be haunted by tiny voices. I don't know if I can live with myself after making a bunch of six year olds sad on their special day," said Molly. "Think of it as redistribution of wealth. Those rich parents can buy more presents. We'll be doing the economy a favor by moving merchandise. Now for the escape we use the trampoline to jump the fence. It's perfect comedic heist material. Are you with me or not?" "I'm with you Bill but this better not end with us in tiny handcuffs. Okay let's synchronize our watches and go steal some joy from the youth. One more thing make sure we don't take the stuffed bear it looks too much like my old teddy and that would just be weird for me."
