"Okay, so run it by me again," Molly said, "because last time you had us disguised as clowns and that ended with you in a headlock." "That kid bit like a wolverine, how was I supposed to know?" "You were supposed to know because they're children, Bill. Small, feral, and quick." "Fine. New plan. We're the bouncy castle guys." "We don't own a bouncy castle." "We rent one. Cash only. Set it up, wait till everybody's distracted bouncing their brains loose, then we grab the presents from the gift table and we're gone before cake." "And if a parent asks who we are?" "We say we're with Jumpin' Jerry's Party Rentals." "Is that a real company?" "It is now. I made business cards." "You made business cards." "Laminated, even. Very professional." "Bill, this is a six-year-old's birthday party. There will be balloons shaped like dinosaurs and a bounce house shaped like a castle and forty presents wrapped in paper with actual unicorns on it." "Exactly. Nobody suspects a unicorn heist." "That's not a real category of crime." "It is today." "You're impossible." "I'm ambitious. There's a difference." "There really isn't." "Are you in or not?" "...Fine. But I'm not wearing the Jerry costume." "Nobody said anything about a costume." "There's a costume, isn't there." "There's a costume."
