Molly and Bill were crouched behind a large oak tree overlooking the bustling children's party in the backyard. They had been planning this heist for days and the time had finally come to execute their comedic caper. "Bill oh this seems like a really bad idea even for us. Stealing from a children's party? The presents are for little kids after all." Molly hissed under her breath while scanning the area for adults. "That's the point Molly. No one will ever expect two thieves like us to crash a kiddie bash. We'll disguise ourselves as magicians and make the gifts vanish like real magic." Bill replied with excitement in his voice as he held up a cheap cape. "But what if the birthday boy figures it out? Kids are smarter than you think." She countered while biting her lip nervously. "We'll distract them with some balloon animals see. I'll twist some dogs and they'll forget all about the presents until we're long gone with the loot." He said trying to reassure her as he practiced his routine. The duo knew it was risky but the thought of unopened boxes filled them with determination and a sense of ridiculous adventure.
