"Bill, this plan is insane but tell me again how we're going to break into that children's party and steal all the presents without getting caught," said Molly. "There will be parents and vicious kids everywhere." "Easy Molly, we arrive as surprise entertainers, a pair of bumbling magicians," replied Bill. "While I do card tricks you load the bags and if anyone asks it's all part of the show. We fake it like always. The kids won't know the difference and the adults will be too busy to notice. Plus we bring our own cake with a file in it just in case." "A file in the cake? That's for prison breaks not birthday parties you moron," said Molly. "This is the worst idea since we tried to steal the Easter bunny. Why are we doing this?" "Imagine the loot Molly all those new bikes computers and stuffed animals we can sell for top dollar. It's perfect," said Bill. "We'll be in and out before the cake is cut. No one will be the wiser. Ready partner?" "Ready as I'll ever be for this madness but if a kid cries I'm out. Let's review the escape route before we put on those polka dot suits and ridiculous noses," said Molly.
