AI
"Okay, Bill, repeat the plan." "We sneak into Tyler's fifth birthday party, steal every present, and leave before cake." "Before cake? Why before cake?" "Because you get emotional at cake, Molly." "That was one time, and it was a dinosaur cake. Nobody should have to watch that get cut." "Focus. How do we get in?" "Costumes. You're the clown." "I hate clowns." "Everyone hates clowns. That's why nobody will look at you directly." "And you?" "I'm the bouncy castle inspector. I brought a clipboard." "That's brilliant. Terrifying, but brilliant." "Thank you. Now, the presents are in the living room, guarded by Grandma Peg." "How do we handle Grandma Peg?" "You fold balloon animals until she's mesmerized." "I only know one animal." "Which?" "A sad giraffe." "Perfect. Sad giraffes are universally distracting." "What if the kids catch us?" "Toddlers are unreliable witnesses. Last time one described me as 'a tall dog.'" "You were wearing a fur hood." "Exactly. Details matter. Ready?" "Wait. If we steal everything, what do we do with forty Lego sets?" "Bill, we're professionals. We build a getaway vehicle." Bill sighed. "Can we at least keep the cake?" "No cake."
