This clip holds a single soft suu vowel for just under a second and a half, wavering a little as it stretches with no words, beat or background noise. It sounds like someone beginning to speak and getting caught on the first sound, which creates an awkward, suspenseful pause. That held tension makes whatever follows feel funnier and more surprising.
