RORY McILROY ramped up the Ryder Cup atmosphere by performing the iconic Viking Thunder Clap with fans on the first tee.
The four-time Major champion, playing in his fifth straight clash with the Americans, got palms stinging on the second official practice day at Le Golf National.
Joined on the tee by Justin Rose, McIlroy flung his hands together and was soon joined by the supporters.
Even Rose's caddy, Mark Fulcher, got involved in the routine made so popular by Iceland during their amazing Euro 2016 run.
McIlroy kick-started the festivities after claiming it would be "silly" for his side to focus solely on beating a resurgent Tiger Woods.
The former world No 1 comes into this week on the back of completing golf's greatest comeback at last week's Tour Championship.
And even with his legend restored, McIlroy, who played with Woods in that final round at East Lake, says he is just one of 12 in France.
He said: "This week he's one of 12. We're not looking at any individuals. We're just trying to beat the US team.
"It's great what he did on Sunday. It was great for golf. It brings a lot of excitement to the game.
"I think to focus on one player is silly, especially when I might not even see him this week at any point.
"I might not be on the course with him or play against him.
"I don't really want to speculate how he's going to play or what he's going to do.
"We're looking to beat the US team. We're not looking to just beat Tiger Woods."
