Molly and Bill sat in the cluttered back of their old van parked across the street from the boisterous children's party. Balloons bobbed in the breeze as screams echoed around them. They were finalizing their scheme to steal all the presents. "Okay Bill, the plan is simple. We strike right after the piƱata but before cake," Molly explained. Bill looked doubtful, twisting his hands. "Molly, this feels wrong. These are little kids we're targeting here," he said. "Wrong? It's just toys. They'll get over it fast," Molly shot back. "But how do we blend in with all those parents watching?" Bill questioned. "We go as clowns of course. I'll handle the face painting station while you distract with bad jokes," she replied. "Bad jokes? I don't even know any kid appropriate ones," Bill complained. "Make them up. Meanwhile I'll be loading the gifts into our fake present sacks disguised as party favors," Molly continued. "What if we get caught by a suspicious mom or the birthday boy himself?" he asked. "Then we activate the smoke bombs and run for it. Simple," she assured him. Bill nodded. The pair prepared their costumes for the heist.
