"Okay, Bill, here's the plan. We slip in through the bouncy castle, grab the presents from the pile by the cake, and we're out before the clown finishes his balloon animals." "Why the bouncy castle, Molly? That thing's got more kids in it than a school bus." "Exactly. Nobody notices two extra bodies bouncing around. We blend in." "I'm forty-three years old, Molly. I'm not blending in with a bunch of sticky six-year-olds." "Then wear the pirate hat. Nobody questions a pirate." "Fine. And what if somebody asks why I'm carrying a sack?" "Tell them it's a goodie bag. Say you're the uncle who forgot the gifts." "Right, and who's going to believe that?" "Bill, the little one in the dinosaur costume just waved at you. Wave back, and look like you belong." "Oh no. He's coming over." "Smile, Bill. Smile like it's your birthday." "Hi, kid. Nice dinosaur." "Thanks! Are you the magic man?" "Uh, yes. The magic man. Molly, what do I do?" "Make a rabbit disappear, Bill. Make a rabbit disappear."
