Molly unfolded the blueprint across the hood of the van. "Okay, Bill. Bouncy castle at eleven o'clock, clown at two o'clock, piñata—dead center." "What about the kids?" "What about them?" "They're, like, everywhere, Molly. They're a swarm. They're a biblical plague in sparkle shoes." "That's why we wear the costumes." "I'm not being a clown." "You're being the clown, Bill. I already called princess." "Why do you get to be princess?" "Because I have the tiara, Bill. I have committed to the bit." "Fine. What's the extraction plan?" "Simple. You distract with balloon animals, I sweep the gift table, we meet at the minivan." "I can't make balloon animals." "Make a snake. A snake is a straight balloon, Bill. A snake is literally the balloon." "And if someone asks for a giraffe?" "Tell them the giraffe is extinct." "Giraffes aren't extinct." "They are at this party." "What about the parents?" "Drunk on boxed wine by one-fifteen. Window closes at two when the sugar crash hits." "And if we get caught?" "We cry, Bill. Loudly. Nobody arrests a sobbing princess." "That's the whole plan?" "That's the whole plan."
