"Bill, tell me you've got the plan memorized." "I've got it. Balloon guy costume, sneak in through the bounce house, grab the presents from the gift table." "That's not a plan, that's a fever dream." "You said keep it simple!" "Simple, not insane! There'll be forty screaming eight-year-olds in there, Bill. Forty. That's forty sets of eyes." "Kids don't notice anything except sugar and cake." "They notice everything! Kids are basically tiny detectives with juice boxes." "So what's your genius plan then?" "We dress as the entertainment. Magicians. Nobody questions magicians." "We don't know magic tricks, Molly." "We know one trick. Making presents disappear." "...That's actually not bad." "Thank you." "But what if the real magician shows up?" "Then we improvise. Say there's two of us this year. Twins. Very popular in the industry." "Magician twins." "Magician twins who desperately need cash and have zero moral compass, yes." "I like it. What about the parents?" "Parents are on their phones the entire time, Bill. We could steal the bounce house and they wouldn't notice." "Bold claim." "I stand by it." "Fine. Magician twins it is." "Wear the cape with dignity, Bill." "I always do." "You really don't."
