Death, taxes and banter between Bryson DeChambeau and Brooks Koepka until the end of time.
It is understood that not everyone enjoys the "feud" between these two PGA Tour professionals and Ryder Cup winning team mates.
There was reportedly legitimate bad blood there even without the gold carrot of the player impact money.
Before the Ryder Cup this rivalry appeared to simmer down and we were treated to fluffed up PR pieces from the United States.

Hyped up music captured Koepka walking over to DeChambeau with the caption: "Team mates talk".
Yeah, that's definitely not one for the cameras.
Justin Thomas saw the rivalry in a different light when he forced the two to hug in one of the funniest press conferences we have ever seen.
The Americans sang "Why can't we be friends" as the pair hugged it out after battering Europe 19-9.
DeChambeau, 28, appears keen on continuing this "feud" at least for the foreseeable future.
A video on his Instagram posted last night shows him telling his followers: "Check out this brand new prototype that y'all can't even see".
As the camera pans back instead of the new club we see that famous annoyed face of Koepka, 31, that spread on the Internet like wildfire.
In typical fashion DeChambeau sends Koepka's face down the range to the enjoyment of his legion of fans.
Koepka responded: "At least you hit that one straight"
Justin Thomas commented: "Does that driver work ok?"
It looks like the driver works okay, we can't wait to see what it will look like and how DeChambeau will perform in 2022.
DeChambeau first up have agreed to play each other in Las Vegas for the fifth edition of The Match.
