Molly and Bill crouched behind the bouncy castle with binoculars. "Remember, we grab the presents and leave before the clown arrives." Bill adjusted his striped party hat nervously. "Are you sure stealing from seven year olds is our lowest job yet?" Molly checked her clipboard and frowned. "Relax, the birthday boy gets double presents every year anyway." Bill peeked through the fence at screaming kids. "What if parents call the police over missing loot bags?" Molly rolled her eyes and lowered her voice. "Then we blend in, sing happy birthday, eat cake." Bill scratched his fake mustache thoughtfully. "I hate cake, frosting sticks to my ski mask." Molly pointed toward the gift table piled high. "Focus, Bill, we need the big box with the bike." Bill sighed and examined the backyard escape route. "Fine, but I refuse to pop any balloons for cover." Molly handed him an empty pillowcase for loot. "Deal, you grab gifts while I distract the magician." Bill groaned loudly as children chanted inside. "Stealing toys feels wrong, but rent is due soon." They fist bumped and crawled toward the gate ready to crash the happiest heist ever attempted by bumbling thieves today in broad daylight together.
