"Right, so the birthday kid turns seven at two o'clock," Molly whispered, unrolling a crude crayon drawing onto the table. "Is that our blueprint?" Bill squinted. "Did you draw this yourself?" "I had to improvise. The architect wasn't available." "Molly, you've drawn the bouncy castle bigger than the house." "It's to scale." "It absolutely is not to scale." "Focus, Bill. We enter through the garden gate during musical chairs. Everyone looks left, everyone looks right, nobody watches the present table." "What about the clown?" "What clown?" "Every children's party has a clown, Molly." "We're not afraid of clowns." "Speak for yourself." "Bill." "I'm just saying he'll have a clear sightline from the balloon station." "We disable the clown first." "And how exactly do we disable a clown?" "We take his bicycle horn." "That's your whole plan? Take his horn?" "A clown without his horn is nothing, Bill. He's just a sad man in makeup." "I genuinely cannot argue with that." "Then we grab the presents, load the van, and we're gone before they cut the cake." "What kind of cake?" "Irrelevant." "Is it chocolate?" "Bill, please."
