In the 92nd minute at St Mary's, Cedric Soares took aim from 30 yards and planted a tame shot into the gloves of Heurelho Gomes.
It was met by the loudest cheer of the afternoon from the Southampton fans, an ironic appreciation that their shot-shy side had finally mustered an effort on target.
Not that many of the home faithful had stayed that long. The exodus began when Daryl Janmaat doubled Watford's lead midway through the second-half and jeers greeted the final whistle from those who stuck it out.
You couldn't blame them for venting frustrations - this was a film they'd seen before.
