"So we're really doing this?" Bill asked. "Stealing from kids?" "Not kids. Presents," Molly said. "There's a difference." "What difference?" "The presents won't cry when we take them." "The kids will." "Then we work fast," she said. "In and out before the cake." "What's the plan?" "You distract them. I grab the loot." "How do I distract a dozen seven-year-olds?" "You're dressed as a clown, Bill. Clown around." "I hate clowning." "Nobody hates clowning." "I do. Deeply. It's why I left the circus." "You left the circus because you stole the elephant." "Borrowed." "You can't borrow an elephant!" "I gave it back!" "To the wrong zoo!" Bill crossed his arms. "Fine. I'll clown. But you owe me." "I'll buy you a balloon animal." "I want a real animal." "We are not stealing another elephant." "A goldfish, then." "Deal," Molly said. "Now, when I signal, you do the honking nose thing." "I don't have a honking nose." "Then honk verbally." "That's humiliating." "So is prison, Bill. Honk for freedom." He sighed. "Honk." "Louder." "HONK." "Perfect. The presents won't know what hit them." "And the kids?" "They'll remember this birthday forever." "That's the saddest thing you've ever said." "Get in the van, Bonkers."
