Molly and Bill huddled in their hideout, planning the heist of a lifetime. The target was an innocent looking children's party full of presents waiting to be stolen. The pair had pulled off many adult oriented robberies but this one was special and full of potential for comedy and disaster in equal measure. Bill was nervous but Molly was convinced it was a brilliant idea. "Bill, we need to hit the children's party right after the magician finishes his act. That's when they'll be opening the presents," said Molly. Bill shook his head. "I don't know Molly, stealing toys from kids feels wrong. Can't we rob a bank instead?" Molly rolled her eyes. "No banks have better security. This is easy money. We go in as party clowns and slip out with the bags full of gifts while the kids are busy with games." He sighed deeply. "What if the parents catch us or the birthday boy starts crying?" She grinned. "We'll have a backup plan with smoke bombs that look like party poppers. Trust me, this will be our most hilarious heist yet." They both laughed at the ridiculousness of the situation as they finalized the details for their comedic caper.
