“Listen, Bill, it’s foolproof. We hit the bouncy castle at exactly three o’clock, right after they sing Happy Birthday.” “Mol, it’s a kiddie party. There’ll be clowns. I hate clowns.” “Which is why you wear the rubber-nose disguise, genius. I’ll be the slightly tipsy aunt who ‘accidentally’ spills punch on the gift table. You roll up behind me in the walker we stole from the nursing home.” “A walker? At a six-year-old’s party?” “Gives you character. Plus it’s got a hidden compartment for the Xbox and the giant stuffed unicorn. Now, when the piñata explodes, that’s our cue. Every brat stampedes, we snatch every glittery box in sight and waddle out like we’re late for bingo.” “What about the parents?” “Parents are too busy filming vertically on their phones to notice two pros. Worst case, we yell ‘Who wants ice cream?’ and bolt during the sugar riot.” “I still say the clown costumes were better.” “Last time you wore clown shoes you tripped over a toddler and nearly got us pinched at the mayor’s daughter’s tea party. We’re doing it my way: fake walker, fake limp, real presents. You in or not?” “Fine. But if a kid asks me for a balloon animal, I’m blowing the whole job.” “Deal. Now pass the juice boxes. We need to practice looking innocent.”
