"So we're really doing this?" Bill asked. "Robbing a kid's birthday party?" "Keep your voice down," Molly hissed. "And yes. Think about it. Hundreds of presents, all wrapped, all unguarded." "Unguarded? There'll be like forty children there." "Children, Bill. We're grown adults. What are they going to do, throw juice boxes at us?" "My cousin got concussed by a juice box once." "Your cousin gets concussed by everything. Focus. We go in dressed as the entertainment." "What entertainment?" "Clowns, Bill. We go in as clowns." "Absolutely not. I have a fear of clowns." "You're going to *be* a clown." "That doesn't help! That makes it worse!" "Fine," Molly groaned. "You can be the magician." "Magicians steal things all the time. That's perfect cover." "See? Now you're thinking." "And while I do card tricks, you load the presents into the van?" "Exactly. We're in, we're out, we're rich." "Rich off Hot Wheels and stuffed animals." "Those stuffed animals retail for thirty dollars each, Bill." "You've researched this." "I've researched everything. Pin the Tail on the Donkey starts at two. That's our window." "Why then?" "Blindfolds, Bill. Everyone's wearing blindfolds." Bill paused. "Molly, that's genuinely brilliant." "I know," she grinned. "Now grab the fake mustache."
