Less downed, more drowned.
Before the cascade of champagne to mark Wales' glorious Six Nations Grand Slam, one which propels their coach Warren Gatland and the players into the pantheon, came the flood.
Here Wales pushed Irish heads under the surface of the rising stormy waters in Cardiff and held it there all afternoon.

Roof open, the rain was relentless. But so was Alun Wyn Jones – now Wales' seventh triple Slammer – so was Adam Beard, the youngster who has now won all 13 of his Tests, and so was Gareth Anscombe.
His best day in red by a distance, Anscombe had to move to full-back but ran the show, kicked his goals and vindicated every ounce of faith Gatland has shown in him.
Desperate for Anscombe to have a big game in a big game, Gatland has persevered with the Kiwi-convert No 10 and boy this re-payed all that.
Twenty points for him, as Hadleigh Parkes took the only try, a 12th Slam for Wales, and around 275,000 in Cardiff's city ready to down countless celebratory pints.
Oh the intense irony of it all. It was Ireland on Thursday who sent an email into the Welsh Rugby Union's inbox asking for the Principality Stadium roof to be open, it was Joe Schmidt who played dumb in his press conference, it was Rory Best who said Ireland decided 'to play rugby outdoors' before this.
And at half-time it was Ireland who were sloppy, Ireland caught in the storm, Ireland drowned in the rain.
In a perfect book-ending of Wales' tournament – and one which summed up how far they had travelled in this Six Nations – they were 16-0 up and cruising in a downpour.
It was on the opening night in Paris where they had flapped, argued and rued their luck, 16-0 down at the break to France.
Then came the comeback at the Stade de France. At half-time here, though, nothing of the sort was on the cards.
Wales do not lose these games. They always seem to travel home for the Grand Slam, and in the Six Nations era they have never fallen short. And they were not to here.
With Storm Hannah's rain pelting down heavier by the minute – the roof open on Ireland's request – Wales came flying out of the blocks.
It was a chastening experience for the Irish players as they were comprehensively swept aside by the championship winners
Liam Williams, the Wales full-back, tries to launch a break as the hosts attempted to establish a stranglehold on the contest
Seventy-one seconds was all it took for the first try, and it was if the crowd had sucked the ball over the line. From the kick-off George North banged the catcher into touch on the far side, and Wales set their move in motion. A maul, two carries before Anscombe flicked an audacious kick down chip alley for Parkes.
The head-banded centre caught it and scored. When Wales won their last Grand Slam in 2012, the Kiwi-convert pair were making their Super Rugby debuts in South Africa –
