The two thieves sat in a dimly lit room surrounded by heist equipment and half eaten takeout. Molly was enthusiastic while Bill was filled with doubt as they planned their most unusual caper yet. "Bill, the key to this entire operation is timing it perfectly with the birthday cake being served. That's when all the kids and parents are distracted in one room. We sneak in through the back during the magic hour," Molly said as she pointed at the clock on the wall. Bill scratched his head and frowned deeply. "Molly, I still can't believe we're doing this. Stealing presents from a children's party sounds like something a cartoon villain would do. What if we get caught by a bunch of six year olds? Our reputation would be ruined forever." "Don't be ridiculous. Kids are gullible. We'll disguise ourselves as party performers. I'll be the magician and you can be my clumsy assistant. While I keep them entertained with card tricks and disappearing coins, you can start collecting the gifts from the table and put them in our special sack that looks like a giant birthday gift," Molly responded while demonstrating a coin trick poorly with a coin falling to the floor. "That might work for a few minutes but those parents are going to be suspicious of two new faces. And my clumsy assistant act is a little too close to reality. I might knock over the whole table. How are we supposed to get away with bags full of stuff without anyone noticing?" Bill questioned as he stood up and started pacing the floor nervously. Molly leaned forward with excitement in her eyes. "That's where the fake fire alarm comes in. I have a small device that will trigger the smoke alarm at the perfect moment. In the chaos everyone will evacuate and we'll load up the van which will be parked in the neighbor's driveway. By the time they realize the presents are gone we'll be halfway across town laughing about it all the way to the bank." Bill stopped pacing and looked at her with a mix of admiration and fear. "A fake fire alarm? That's pretty smart actually. But what if real firefighters show up? This could escalate quickly. And you know how I feel about kids. They always want to hug me and I end up with sticky fingers all over my favorite jacket from the cake." "We'll be in and out so fast they won't have time to hug anyone. Just remember to wear the silly hat to hide your face. After we fence the toys at the underground market we can finally afford that vacation we've been dreaming about. No more living hand to mouth on ramen noodles," Molly assured him while packing some tools into a large black bag. "Okay, I'm starting to like this plan against my better judgment. Let's go steal some presents from those little monsters. But if anything goes wrong it's your fault and I'm retiring from this life for good," Bill said with a laugh that echoed in the small room. "Deal. This is going to be our funniest heist yet," Molly replied with a wink.
