“Bill, you’re joking. A children’s party? We’re stealing from toddlers now?” “Toddlers with rich parents, Molly. Those presents are stacked like a department store. One piñata, one clown, and we’re golden.” “I draw the line at clown. I’m not fighting a man in floppy shoes.” “You won’t have to. I’ll dress as the clown. You be the pony.” “I am not wearing hooves for this.” “Fine, you’re the balloon lady. Just act surprised when they pop. That’ll be our signal.” “Our signal is popping balloons? Genius. What’s next, we yell ‘Happy Birthday’ while cracking the safe?” “There is no safe, love. Just a bright pink treasure chest under the gift table. We grab it, shove it in the bouncy castle, and bounce our way out.” “You want to escape in a bouncy castle.” “Kidnapping the castle is half the plan. Distraction, see? While they chase the rogue inflatable we leg it with the swag.” “I hate you. I’m in, but if I get glitter in my hair I’m framing you for the Great Cupcake Heist of ’19.” “Wouldn’t be the first time. Pass the juice boxes—we’re going in dry.”
