The two thieves had been planning this caper for days but the target made it all the more absurd. In the dimly lit back alley hideout, Molly and Bill hunched over their map. The air smelled of old pizza and anticipation. Molly peered at the stolen invitation. "Bill, this party has twenty kids and presents. We strike during musical chairs." Bill rubbed his chin as he adjusted his glasses. "Musical chairs? Molly, how do we avoid the tattle tales?" With a mischievous glint, Molly continued. "We dress as the pony. I'll be the front, you the back. No one will suspect the pony." "The pony? Have you lost your mind? Last time I got peed on by a dog," Bill exclaimed. Trying to calm him, she put a hand on his shoulder. "Stop complaining. Once we have the presents, we vanish into the crowd of parents. Act like we are returning a gift." Bill looked skeptical. "Returning a gift? With a sack full? You are crazy but I like it. What about the birthday boy?" "He will get over it. We leave him a sock. Now let's practice our neighs," Molly laughed. Bill shook his head but smiled. The plan was stupid but it might just work in the most hilarious way possible.
