Molly and Bill sat plotting their next move. "Bill, we are breaking into the children's party to steal all the presents. Get your clown suit ready because we're going in as entertainers. Distract with jokes and balloons while I swipe the gifts. Ignore the screams and focus on the gift table." "Molly, this is crazy. What if the kids see through our disguises? They have eagle eyes for fakes. And the mom with the camera will photograph everything." "Ignore that, Bill. We'll be in costumes from the theater shop. It's perfect. The presents will be ours by the time they play musical chairs. Think of the money from selling video games and dolls." "But it's a kid's party, Molly. I feel bad." "No way. All or nothing. Stop being a wimp, Bill. This is the heist of the century for us. Are you with me or not?" "Yeah, I'm with you but if we get busted it's your fault." "Good, now let's go over the exit strategy again. The backyard fence is our way out after we load up." "The fence? Last time I ripped my pants on one. But okay, Molly, if you say so."
