Bill whispered to Molly, "How are we going to break into that children's party to steal all the presents without anyone noticing us at all?" "We go as clowns Bill. While I make balloon animals you grab the gifts and stuff them quickly in the clown car. The kids will never suspect a thing from us," she replied. "Clown car? That's brilliant Molly but what if they ask us to do magic tricks? I can't pull a rabbit out of my hat to save my life or anyone else's for that matter." "Then we skip the tricks and go straight to the piƱata instead. I'll swing blindfolded to create a big distraction and you sack all the presents during the scramble. It's perfect in every way." "Perfect? Last time we used a distraction you hit the wrong target completely. But okay I'm in if you promise not to swing that bat anywhere near me at any time." "I promise Bill. No hitting the partner ever. After we have the loot we yell banana split and run for it as fast as we can. This will be our funniest heist ever by far." "Funny until the parents catch us red handed. But you're right it's time to hit the children's party hard this time. Let's get those presents before they open them all up."
