Shane Lowry is well known to be one of the bubbliest characters on the PGA Tour, and his exuberant celebrations were arguably the highlight of Europe's Ryder Cup triumph last year.
The Offaly man lets his emotions show on the course and that can occasionally lead to frustrations slipping out.
One infamous incident in 2016 saw Lowry caught swearing loudly after a wayward tee shot at the Honda Classic in Florida.
Lowry shared his frustration that day with playing partner Smylie Kaufman, as both men skewed their shots into the water. The pair recalled their experience of being scolded by PGA Tour officials this week.

Shane Lowry had brilliant reaction to classic F-bomb clip from 2016
Lowry appeared on Kaufman's podcast 'The Smylie Show' this week, and the pair played the classic clip of the Irishman's foul-mouthed outburst on the 15th tee of the 2016 Honda Classic.
Within milliseconds of his strike, Lowry can loudly be heard exclaiming, "Ah, you fucking idiot!"
The commentators on duty quickly apologised for Lowry's language at the time - and the 2019 Open champion revealed that he also got in hot water with the PGA Tour for his outburst.

Seconds before Lowry's wayward shot, Kaufman had similarly smashed his tee shot into the water, and reacted by snapping his club in half.
The duo revealed this week that they had been called in by PGA Tour officials to address their furious reactions on the tee box - and Lowry had the perfect response to his fine:
I was trying to cut a little 7 iron in as well - I cut it alright! A little too much...
Ah, yes! I remember getting called into the office the following week. It was like getting called into the principal's office.
I got fined or whatever. I remember saying, 'yeah, I'm sorry, but I can't promise you that it's not going to happen again!'
We'd expect nothing else from Shane Lowry.
The Irishman is in contention after the first round of the Classic this weekend, sitting three shots off tied leaders Chad Ramey and Kim Seong-hyeon in the leaderboard. He is level with fellow Irishman Rory McIlroy in T18.
Lowry tees off on Friday at 17:29 Irish time, with McIlroy getting underway in the following group at 17:40.
