"Bill, tell me you have the plan." "I have a plan." "A good plan." "I have a plan, Molly. It's a birthday party. There's cake. There's a bouncy castle. There's presents. We take the presents." "That's not a plan, that's a wish." "Fine! We dress as clowns, we do a magic show, we distract the parents, we grab the loot, we vanish. Better?" "You can't do magic, Bill." "I can pull a quarter from behind a kid's ear!" "You dropped the quarter last time and made him cry." "He was already crying! It's a five-year-old's birthday, they cry about everything!" "We need a better cover. What if we're the entertainment? Face painting." "I can't paint faces." "You can't do magic either, but that didn't stop you." "Touché. Face painting. You paint, I grab the presents." "And the bouncy castle?" "What about the bouncy castle?" "Someone has to hold it down while we load the van." "Why do I feel like that someone is me?" "Because it is. Now get the face paint, clown boy." "I'm not a clown anymore, I'm an artist." "You're a thief, Bill. Same as me. Now move."
