WATCH: Shane Lowry and Rory McIlroy have absolutely great craic after winning the Zurich Classic in New Orleans

Shane Lowry and Rory McIlroy won the Zurich Classic in New Orleans in dramatic fashion on Sunday with Lowry holing a birdie on the last hole in regulation to force a playoff before the Irish duo went on to win on the first extra hole.

After a slow start to the final round, they came with four birdies in five holes around the turn and birdies on 16 and 18 to get them to 25 under par.

That left them level with Martin Trainer and Chad Ramey but the American's were wayward on the playoff home and McIlroy tapped in from the edge of the hole to win it for the Irish pair. 

But based on videos posted to social media platforms, that was only the start of it for the long time friends as they celebrated their win in the Big Easy. 

Firstly Shane had some difficulties with his winners belt as he can be heard telling Rory 'it's a bit snug' which sends McIlroy into fits of laughter. 

With one belt one and one belt in hand, and beads around their necks they can be seen being led by a jazz band to continue the celebrations...

... and then there was this.
