As Colin Montgomerie is left to smoulder after Sandy Lyle's withering verbal onslaught this week, he must be rueing the fact that he ever went to Indonesia at all four years ago.
Lyle, still clearly riled by the fact Monty will be Ryder Cup captain in Wales next year, has - for reasons known only to him - dredged up a dropped ball incident four years ago and despite issuing fulsome apologies, keeps firing barbs under his breath.
Colin Montgomerie ignores Sandy Lyle
Blank look: Colin Montgomerie ignores Sandy Lyle as the two cross paths at The Open this week
Lyle accused his fellow Scot of being a 'drama queen' and hiding behind his manager' just after saying he wanted to draw a line under the whole thing.
If they ruin Monty's Ryder Cup preparations, Lyle's words could even be construed as treason.
But the Scottish heavyweight clash is merely the latest in a long line of sporting spats, pools of disagreement that became roaring seas of discontent.
Sportsmail decided to take Lyle's lead by dredging up a few old sporting verbal jousts. And one-name dominates.
Sir Alex Ferguson v.
The 1999 Treble-winning defender was sold in 2001 after offedning the boss with a series of revelations in his autobiography.
David Beckham shows why you should never get in the way of an Alex Ferguson 'flying boot'
After 'flying boot-gate' in 2003, Sir Alex's hatred of Beckham's celebrity lifestyle bubbled over and he soon sold the England skipper to Real Madrid.
He irritated the boss with his self-penned 'Guv'nor' nickname and was sold to Inter in 1995 with Sir Alex labelling him a 'big-time Charlie.'
Ruud van Nistelrooy
The boss would not put up with the Dutchman - despite 150 goals in 219 appearances - after a training ground clash with Cristiano Ronaldo.
Wanted to leave United for Liverpool in 2007 so Sir Alex duly offloaded him - to Real Madrid.
Accused the Liverpool manager of 'cracking up' this year as their title bid faltered, rendering the Spaniard almost incandescent with rage when he added Robbie Keane wasn't worth the money.
Famously reduced King Kev to a frothing heap when he accused teams of playing well against United and not so hard against title-chasing Newcastle. 'I would love it,' etc.
Claimed he 'wouldn't sell a virus' to the Spanish giants last year before offloading Cristiano Ronaldo to them this summer for £80m.
Slammed the Arsenal boss in 1997 when insisting: 'he's a novice and should keep his opinions to Japanese football.' The two have clashed regularly since then, including 'Pizza-gate' in 2004 when United ended the Gunners' 49-game unbeaten record, leaving Wenger at one stage promising never to mention 'that man' again.

Many a third official has had to come between Arsene Wenger and Sir Alex on the touchline down the years
Tonya Harding v Nancy Kerrigan
The world of ice-skating blundered into Mafia territory in 1994 when the top two in the US hit the headlines. Harding's husband Jeff Gillooly hired someone to attack Kerrigan, who missed the subsequent US Championships with an injured knee. Harding denied all knowledge - then admitted helping cover up the attack and was banned for life as a result, after the US authorities originally ruled she had indeed not been involved in the attack.

Danny Cipriani v Josh Lewsey
Only one winner here when the ex-Army man Lewsey disagreed with Cipriani at Wasps training last year. Words were exchanged - then Cipriani emerged with cuts to his nose and lip.

Mike Gatting v Shakoor Rana
The most famous player/umpire clash in cricket. In 1987 during the second Test, Rana accused England captain Gatting of moving his fielders without the batsman's knowledge. Gatting accused the umpire of overstepping his mark and the two stood face-to-face in the Faisalabad heat, wagging fingers at each other. Rana walked off and wouldn't play until Gatting said sorry - which he did but not for six hours.

Dennis Lillee and Javed Miandad
Umpire Tony Crafter gets between Dennis Lillee and a bat-wielding Javed Miandad
Dennis Lillee v Javed Miandad
At Perth in 1981, Miandad was obstructed by the Aussie bowler while trying to take a quick single. He shoved Lillee who responded by kicking him. The umpire had to stand between the two as Miandad advanced towards Lillee with his bat raised over his head while the Aussie faced him adopting a boxer's stance.
Thomas Bjorn v Ian Woosnam
When Woosie didn't select the Swede for the 2006 Ryder Cup, Bjorn branded the Welshman 'pathetic' and 'barmy'. Hardly a heinous crime but it shook the normally placid world of golf.
Fernando Alonso v Lewis Hamilton
There's genuine loathing here. The former McLaren team-mates have not exchanged a word since Hamilton ignored team orders at qualifying for the 2007 Hungarian Grand Prix. Alonso left for Renault at the end of the season and Hamilton was crowned world champion a year later.
Roy Keane v Mick McCarthy
Republic of Ireland skipper Keane walked away from the World Cup in 2002, citing substandard training facilities. He also laid the blame at the feet of manager Mick McCarthy. Among of plethora of XXX-words and oaths, Keane told the boss: 'Mick you're a liar. I didn't rate you as a player, I don't rate you as a manager, I don't rate you as a person. The only reason I have any dealings with you is that somehow you are the manager of my country. You can stick your World Cup.'
