Molly tapped the blueprint spread across the dashboard. "So we go in through the bounce house?" "Absolutely not. Those things are death traps." "Bill, you're six foot three. Just climb the fence." "And alert the parents? No way. We dress as clowns." "I'm not wearing a clown suit again. Last time you locked me in that car trunk for two hours." "That was strategic! Besides, who invites twenty kids and doesn't hire entertainment?" "Rich people, that's who. Which is why we're here." "Right. So clown suits?" "No clowns, Bill." "Fine. We could pose as the pony." "What?" "The pony. Two-person costume. I'll be the front, you're the rear." "I hate you." "You love my ideas. Once we're inside, I'll fake a pony emergency." "A pony emergency." "Yeah, like I'm choking. You grab the presents during the chaos." "This is your worst plan yet." "You said that about the aquarium job." "We almost drowned!" "But we didn't. So we're doing the pony?" Molly sighed. "Get the costume."
