“Bill, you’re joking. A kiddie party? We’re not stealing candy from babies.” “It’s not candy, Molly—it’s presents. Twenty screaming moppets, one giant pile of wrapped glory. We’ll be in and out before the piñata hits the floor.” “You want us to crash a bounce house in ski masks? That’s not a heist, that’s a felony with frosting.” “No masks. We’ll wear the giant mascot costumes from the supply closet. I’m the dancing dinosaur, you’re the depressed unicorn. Kids’ll think we’re hired entertainment.” “I refuse to be the depressed unicorn, Bill.” “Fine, you’re the sparkly T-Rex. Look, we drop in during musical chairs, I cut the lights, you wheel the gift table out like it’s on casters. We’ll have it in the van before they finish ‘Happy Birthday.’” “What about the parents? They’re not exactly blind.” “Parents are glued to their phones filming little Timmy. By the time they look up we’ll be two blocks away arguing over who gets the Lego Star Destroyer.” “I still say this is the dumbest idea you’ve ever had.” “Dumber than the time we tried to rob the police auction?” “…Start the van, you giant lizard.”
