Molly and Bill sat in their van reviewing the plan to steal presents from the children's party. The idea was comedic in its absurdity but they were desperate. The air was thick with the smell of impending adventure and cheap face paint. They knew this was a new low but the heist books would write themselves if they succeeded in this caper. Bill was dressed in a practice outfit that made him look like a rejected circus reject with baggy pants and a bright red nose that kept falling off. Molly looked equally silly in her painted on smile and polka dot dress that clashed with her serious expression. They had spent the last hour arguing over the ethics of robbing children but the lure of free merchandise won out in the end. The party across the street was in full swing with balloons floating and laughter echoing reminding them of the ticking clock on their opportunity. "Listen Bill this is our ticket to easy street. All those presents just sitting there wrapped and ready for the taking. We go in as the hired entertainment" Molly said. "Yeah but what if the real entertainment shows up? We can't have two magicians or we'll blow the whole thing" Bill responded. "We take care of that easy. You spike the punch with a laxative so the real guy is out of commission. Then it's our show" she explained. "That's harsh Molly even for us. It's a children's party not a mob hit. Maybe just distract him with free tickets to the zoo instead" he suggested. "Okay fine no laxatives. But we need to be convincing. You do the magic tricks and I'll handle the face painting while we case the joint for the present table" Molly replied. "Deal. My disappearing act will have all the kids distracted while you bag the loot. But what about the birthday boy? Won't he notice his gifts vanishing" Bill asked. "We leave him a note saying the presents went to a good cause like us. No wait that's stupid. We just work fast. In and out in ten minutes tops" she answered. "Ten minutes? With all those screaming kids and helicopter parents? You're dreaming Molly. We need at least twenty to properly clean them out" he argued. "Twenty it is then but no more. And remember our code. No stealing the cake or the goodie bags. Presents only" Molly stated. "Focus Bill. The van will be waiting with the engine running. We load up and head straight to the fence who deals in hot toys" she instructed. The comical duo knew this job would test their skills in new ways as they prepared to mingle with the energetic crowd of youngsters and suspicious adults. Success would mean a nice payday but failure could mean public humiliation or even a chase by angry parents. The stakes were high but the potential for laughs was higher as they embarked on this unusual mission that would surely go down in their personal history as the silliest yet.
