Scotland sent out a statement before their first men's World Cup in 28 years with a scarcely-believable final friendly victory against Bolivia at a sweltering Sports Illustrated Stadium in New Jersey.
Four first-half goals had supporters gawping in disbelief - and perhaps even checking the date of the final - as Steve Clarke's side ran riot a week before their Group C opener against Haiti in Boston next Saturday night (Sunday 02:00 BST) - live on the BBC.
Following his two goals in the 4-1 Hampden send-off win against Curacao, Lawrence Shankland strengthened his case to start, heading in early on from captain Andy Robertson's deep cross.
The new Rangers striker wasn't the only forward to make his mark, with starting striking partner Che Adams twice finding the net. First, he tapped in a brilliant Ben Gannon-Doak ball before thundering in a low drive in a dream opening 45 minutes.
The returning Scott McTominay doubled the scoring, the classy midfielder leaving Bolivian goalkeeper Guillermo Viscarra flapping, before Adams got in on the act.
Though they did not add to the outstanding first-half tally, Scotland remained hungry, with Shankland's miss at a clear sight of goal the closest of a bunch of near things.
Last Saturday's win was met with tempered enthusiasm because of the Scots' struggles before Curacao were reduced to 10 players, but there was no playing down this comfortable and commanding performance.
That's probably what will please Clarke the most as he reflects on the game during his journey down to Scotland's base camp in Charlotte, North Carolina on Sunday and in the build-up to their first World Cup finals appearance since 1998.
