There's some milk in the fridge that's about to go bad.........And there it goes.

Our reading
An editorial interpretation.
The pause turns a prediction about milk spoiling into an announcement that it has happened. Treating 'going bad' as a precise event the speaker can catch in the moment gives the joke its absurd timing. An ordinary observation becomes a tiny countdown.
