"So we're stealing presents from children," Bill said. "From actual children." "Keep your voice down." "At a birthday party." "It's a *rich* birthday party, Bill. These kids get ponies. They won't miss a few gift bags." "What's the plan?" "You dress as the clown. I'll be the magician." "Why do you get to be the magician?" "Because I'm the brains, and brains do magic." "I don't want to be the clown." "Everyone loves the clown." "Children are terrified of clowns." "Exactly! Fear is a distraction. While they're crying, I make the presents disappear." "That's your whole trick? Stealing gifts and calling it magic?" "It's thematically appropriate." "And how do we carry it all out?" "The bouncy castle." "...The bouncy castle." "We deflate it, load the presents inside, and roll it out the front door like a giant inflatable burrito." "Molly, that's insane." "That's *genius*, Bill." "What if the parents notice?" "They're rich. They're day-drinking by noon. Trust me." "And the cake?" "What about the cake?" "Can I have some cake?" "You're stealing from toddlers and you're worried about *cake*?" "A man's gotta eat." "Fine. You can have cake. *After* the heist." "Deal. Hand me the clown nose." "That's my heart, you idiot. Wrong bag."
