"Okay, Bill, repeat the plan." "We sneak into Tommy Pickering's seventh birthday party, steal every present, and leave before the cake." "Why before the cake?" "Because you cry at cake, Molly." "That was one time, and it had a dinosaur on it." "Focus. How do we get in?" "I'm the clown. You're the balloon guy." "I don't know how to make balloon animals." "Nobody does, Bill. The children just want to believe. Twist something lumpy and call it a giraffe." "What if a parent asks questions?" "Say, 'I'm an artist,' and walk away with dignity." "And the presents?" "We stuff them in the bouncy castle, unplug it, and roll it out the gate." "Roll it? Molly, it's a bouncy castle." "Exactly. Nobody questions a large, fleeing bouncy castle. It's the perfect getaway vehicle." "It'll be deflated." "Then we work fast. Unplug, stuff, sprint." "Sprint with a castle." "Confidence, Bill. Now, do you have the fake mustache?" "Yes." "Wear it." "It itches." "Crime itches, Bill. Now go make me a giraffe." "Molly, this looks like a sad sausage." "Perfect. Tommy will love it."
