Molly spread the blueprint across the kitchen table, which was actually a crayon drawing of a bouncy castle taped to a pizza box. "Okay, Bill, walk me through the plan again, but slowly this time so your brain can keep up." Bill puffed out his chest, his stolen security badge flashing upside down. "We go in through the side gate dressed as clowns. The kids love clowns. Parents trust clowns." "We are not dressing as clowns. Last time you dressed as a clown you cried when a balloon animal popped." "That balloon poodle was aggressively staring at me, Molly. This time will be different. We bring a giant bag that says presents and we just leave with it." Molly pinched the bridge of her nose. The pizza box smelled like pepperoni and bad decisions. "Brilliant. How do we get past the birthday mom? She's got the focus of a hawk." "We distract her. You do your puppet show. You love your puppet show." "My puppet show is a legitimate art form, Bill. Those kids deserve culture." "Exactly. You distract them with culture while I grab the loot. The table has at least twenty wrapped boxes." A fly landed on the blueprint and immediately regretted its life choices. "LEGO? I thought we were taking the gift cards." "We are two idiots who once tried to rob a lemonade stand and got out-negotiated by a nine-year-old." Bill nodded seriously, as if LEGO were a currency he fully understood. "That kid had a very aggressive business model. This is easier. We just have to get past Timmy." "The birthday boy. Intel says he's turning seven and he's got a karate belt. He could be dangerous." "Bill, he's seven. He weighs forty pounds soaking wet. What's he going to do, kick our shins?" The kitchen clock ticked loudly, counting down to the party like a very judgmental timer. Outside, a kid's bouncy castle inflated and deflated with a sad wheeze. "We are not wearing shin guards to a children's party. We need to look normal." "Normal? Molly, we are two adults without children showing up to a kid's party with an empty sack. We're already suspicious." "We have an invitation. You stole it from the kid's backpack." Molly tapped the crayon bouncy castle. It was labeled definitely not a trap in Bill's handwriting. "Fine. So we arrive at three, puppet show at three fifteen, grab the presents at three twenty, and out by three thirty before the cake cutting." "For the last time, no clown costumes. We wear the neon vest that says entertainer. It's less creepy." Bill shifted his weight. The red nose squeaked faintly with each breath. "But I already bought the red nose. It was twelve dollars." "I glued it to my face." Molly stared at him over the blueprint as Bill's red nose wobbled precariously. It was already listing to the left. "You glued it?" "It said extra hold. I thought that was a good thing."
