Molly and Bill huddled in the corner. "Bill we're breaking into the children's party to steal all the presents. It's brilliant because no one suspects clowns." "Molly clowns? Last time I wore that suit I got stuck in a vent. How's this going to work exactly?" "Simple. We arrive as the entertainment do a few tricks then while the kids are busy with the magic show we load the presents into our fake gift boxes which are empty and switch them with the real ones." "That sounds complicated. What if a kid wants to open one right then?" "We tell them it's for later. Trust me. The party will be so chaotic with all the sugar and running around that we'll be in and out in ten minutes flat." "I still think it's risky. Those parents can be vicious if they think you're harming their precious snowflakes." "That's why we have the smoke bombs disguised as party poppers. One pull and we vanish in a cloud of glitter. Come on Bill think of the money. All those unopened boxes full of expensive junk." "Alright you win. But we're not keeping any teddy bears. I draw the line at stealing stuffed animals." "Agreed. Let's go over the timing one more time."
