A short 1.1-second voice clip of someone blurting out 'Are you kiddin' me?' in clear disbelief. The line lands as funny and exasperated at once, the kind of incredulous reaction that makes an unbelievable moment feel even more absurd without needing any extra explanation or setup from the listener at all.
