The getaway van smelled like cheap balloons and desperation. Molly adjusted her clown wig. Bill stared. "Bill, we're hitting little Timmy's birthday because his dad's diamond bouncy castle means rich parents, rich presents." "Remind me why we stooped to stealing Bluey plushies and LEGO sets?" "Because those LEGO sets are limited edition, worth five grand each, you sentimental idiot." "There's gonna be a clown, Molly. A real creepy clown breathing near the Capri Suns." "That's you, Bill. You're wearing the nose. You're Sparky now." "I don't wanna be Sparky. Last time kids smelled fear and kicked my shins." "Perfect. You'll fit right in. While you twist balloons, I grab the present mountain." "And when thirty sugar-crazed terrors realize their loot is gone?" "We drop the emergency glitter pinata and run like hell toward the van." "Glitter? That's even worse than bees, Molly." "Exactly. No parent chases a man covered in glitter and shame. It's foolproof." "If I survive, I want the big dinosaur LEGO set." "Deal, but you have to actually make one balloon animal correctly this time." "I can make a snake. That's something." "A snake is just an unsnapped balloon, Bill. Try harder." "I'm trying, Molly, I'm trying."
