Molly whispered, "Bill, remind me again why we're robbing a six-year-old's birthday party?" Bill adjusted his ski mask. "Because little Timmy's getting a PS5, Molly. And Legos. So many Legos." "Bill, that's a clown outside. A real clown." "Perfect, that's our distraction. You distract the clown, I grab the presents." "Me? Distract the clown? I am terrified of clowns!" "You're a professional thief! Since when are you scared of clowns?" "Since always! You know this! Why can't you distract the clown?" "Because I'm allergic to balloon animals. You know this!" Molly sighed. "Fine. So the plan is we sneak past the bouncy castle, ignore the screaming children, and steal gift bags?" "Exactly. In and out. Nobody suspects two adults at a kids' party." "Bill, we're wearing ski masks at a sunny park." "Okay, new plan. We pretend we're entertainers." "Oh great, what do we entertain with?" Bill paused. "Uh, interpretive gift-stealing dance?" Molly stared. "Bill, that is the dumbest idea you've ever had." "Hey, it worked at the zoo!" "We got chased by a penguin at the zoo!" "And we got away, didn't we? Trust the dance, Molly." "Fine, but if that clown honks at me, I'm stealing his car."
