"So we're really doing this?" Bill asked. "We're really doing this," Molly said. "Stealing presents. From children." "From a child. Singular. One spoiled birthday boy." "That's worse, somehow." "His name is Maxwell. He's turning seven. His parents bought him a pony." "A pony?" "A pony, Bill. These people have disposable ponies." "Okay, but how do we get in?" "Simple. You're the clown." "I'm the what?" "The entertainment. Big shoes, red nose, the whole disaster. You distract the kids." "And you?" "I'm the magician's assistant. While you juggle, I make the gift table disappear." "Into where?" "Into the van. Behind the bouncy castle." "There's a bouncy castle?" "There's always a bouncy castle." "What if a kid recognizes me?" "From where, Bill? Your extensive children's television career?" "I did a cereal commercial in 1998." "Nobody remembers that." "My mother does." "Your mother isn't invited to Maxwell's party. Focus." "And the presents?" "We grab everything wrapped. Sort it later." "What if some of it's socks?" "Then we donate the socks and keep the PlayStation." "There's a PlayStation?" "Bill, there's a pony. There's definitely a PlayStation." "Okay," Bill said. "I'm in." "Good. Now try the nose on." "It honks." "That's the point."
