Place this clip near the start of a money joke, right after the boast, so it sets up the payoff. Follow it with FBI Open Up when the cash turns out to be suspicious, or cut to Ah Shit Here We Go Again when the plan falls apart and the joke needs a resigned ending.
About this sound
This 12-second clip is GLaDOS, the calm robotic AI from Portal, speaking in her measured synthetic voice about $40,000 in cash. Her flat delivery makes the money talk feel funny, awkward and faintly menacing, like a polite robot pointing out something you would rather ignore. It comes from the Portal games, where GLaDOS delivers deadpan lines while testing you.
