"So how do we get in?" Bill asked. "Simple. We dress as clowns," Molly said. "Clowns? I hate clowns." "Everyone hates clowns. That's the point. Nobody looks twice." "What about the kids?" "Kids love clowns." "You just said everyone hates clowns." "Adults hate clowns. Keep up, Bill." "And the presents?" "We stuff them in the balloon bag." "We don't have a balloon bag." "We'll make balloon animals as a distraction, then load the loot." "You can't make balloon animals." "I made a giraffe once." "That was a snake, Molly. It was clearly a snake." "It had a long neck!" "It had no legs!" "Details. Focus. We're in, we're out, we're rich." "Rich? They're children's presents. It's socks and crayons." "It's an upscale party, Bill. Think bicycles. Think gaming consoles." "Now you're talking." "There's a bouncy castle too." "What's that got to do with anything?" "Nothing. I just want to go on it." "We're professionals, Molly." "One bounce." "No bouncing." "Two minutes, tops." "Absolutely not." "Fine. But you're carrying the piñata." "Why are we taking a piñata?" "It's full of candy, Bill. Free candy." "You had me at free candy." "Knew you'd come around. Now grab your nose." "My what?" "Your clown nose. We're going in."
