Team USA's embarrassing start to the Ryder Cup reached a sad new low early on Saturday morning as Bethpage officials attempted to teach fans the words to player chants.

As the sun rose over Long Island, thousands of spectators packed the grandstands in anticipation ahead of the second day of play - but rather than an organic atmosphere, video from among the fans revealed the truth.

In a wild scene, the fans - who had each paid $750 or more for the privilege of being on site - were subjected to a bizarre lesson from officials with microphones, who attempted to teach them words to pre-created chants to boost the atmosphere.

In one video, a woman can be heard saying: 'Slow down, slow down... you guys all took Adderall this morning. Slow down. One, two, clap, one, two, clap.'

To the tune of Queen's We Will Rock You, the fans were then told: 'Here come the lyrics... Scottie, Scottie, Scheffler!'

Loud boos then rang around the course as fans began to object to being told how and when to sing the songs.

'Alright, hold on' the official then added, before roping in a man alongside her who appeared to be dressed as one of the Founding Fathers.

'We're going to try this one more time, and if it doesn't we're going to try the DeChambeau one,' the man then said, before more loud boos ensued.

A few seconds later, the chant was so horribly out of time that fans could be seen covering their eyes.

When the players did eventually make their way onto the first tee a while later, the chant the fans did eventually sing does not appear to have been one with pre-approved lyrics.

'F*** you, Rory' were the lyrics that the rowdy American fans settled on, and McIlroy then responded by spreading his arms wide and blowing kisses back at them. 

The bad blood continued throughout the day, with McIlroy snapping at fans and telling them to 'shut the f*** up' during the foursomes, in which he later sealed another point for Team Europe alongside Tommy Fleetwood.

Heading into the afternoon Four-Balls, Europe led 8.5-3.5 in a remarkably strong first day-and-a-half of the tournament at Bethpage Black. 

McIlroy has so far not lost in any of his three completes matches, winning two and tying the third - alongside Shane Lowry in Friday's Four-Balls.
