In the dim evening light the two experienced thieves prepared for their most unusual job yet as they observed the joyful event. Molly crouched next to Bill in the bushes binoculars in hand. The children's party was in full swing with colorful streamers and a massive pile of presents. "So we wait for the cake to be cut then make our move?" Molly asked. "Yes that's when all eyes are on the birthday boy" Bill replied. "You create a distraction by pretending to be a lost mom and I'll swoop in for the goods." "What if one of the kids sees us and wants to play?" she said. "Then you tell them it's time for a magic trick and make a present disappear into our bag" he said. "This is the worst idea you've ever had" Molly told him. "But think of the profits" Bill said. "Profits from stolen toys? We really are sinking low" Molly said. "It's just this one job then we go straight" Bill promised. "I've heard that before" Molly replied. After finalizing the details of their plan the two thieves waited for the perfect moment to infiltrate the party and execute their comedic heist to steal all the presents from under the noses of the children and their parents.
