Molly crouched behind the minivan, staring at the bounce house. "Molly, are we really going to steal from a six-year-old's birthday party?" Bill whispered. "Shut up, Bill, it's not stealing from a six-year-old, it's stealing from like twelve six-year-olds, it's economies of scale," Molly whispered. "Right, right, the presents, all of them, but there's a clown in there," Bill said. "The clown is the security system, I already factored in the clown," Molly said. "You factored in a clown? What's his patrol pattern?" Bill asked. "He makes balloon animals until he cries in his car, that gives us a four-minute window," Molly said. "Okay, what's the entry point? The front door says no adults unless accompanied by screaming child," Bill said. "We go tactical, we go through the side gate, grab the present table, exfil past the juice boxes," Molly said. "What if they recognize us? We are two grown adults in trench coats at a children's party," Bill said. "That's why you brought the fake mustache for the child disguise, right?" Molly said. "This is my real mustache, Molly, you told me to grow out my disguise," Bill said. "Perfect, you're unrecognizable, now go steal that Paw Patrol castle," Molly said.
