This short clip is a single voice repeating pam three times before stretching the final pam into a long, humming mmmmmmmm that fills its almost four seconds. It feels playful and deliberately dramatic, like someone announcing something silly with too much ceremony for the moment, then holding the last note just long enough to make the wait itself the joke.
