AI
Molly and Bill sat in their van outside the party house planning their heist. "Okay Bill, the plan is foolproof. We crash the children's party as hired entertainers. You do terrible magic tricks to distract the kids and I swap the presents with empty boxes." "Molly that sounds crazy. What if the parents notice the difference?" "They won't because we'll use the chaos of the piƱata. You swing the bat blindfolded and knock the table of gifts into our bag." "Brilliant! But aren't we the bad guys for stealing from little kids?" "Who says the kids deserve all those toys? We're leveling the playing field. After this we'll be set for beer and pizza for a month. We pull this off and the kids will never know what hit them. It's the perfect crime." "Alright I'm in. But I get first pick of the toys. I always wanted a remote control car." "Bill focus! After we have the loot we run to the car yelling the clown is chasing us so no one follows. Got it?" "Got it Molly. This is gonna be hilarious." "Just make sure you don't eat all the cake like last time or we'll get caught again."
