It's no secret that Brooks Koepka and Bryson DeChambeau aren't the biggest fans of each other, and their beef has been renewed thanks to previously unaired footage that made its way to the internet on Monday night.

After one of his rounds at the PGA Championship, Koepka did an interview with Golf Channel's Todd Lewis. In the middle of the interview, DeChambeau walked behind Koepka, throwing off the golfer's concentration and resulting in a bunch of curse words being thrown about.

This is truly hilarious:

Of course, the internet went absolutely bonkers over the video, quickly turning Brooks Koepka's reaction into a meme:

There's plenty more where all this came from if you want to see more great reactions.

As noted, there's a lot of history between these two men, as documented by Charles Curtis of USA TODAY Sports' For The Win. It seemingly started back in 2019 when Brooks Koepka was among a group of players to complain about Bryson DeChambeau's slow pace of play. The two have gone back and forth since then, tossing jabs on social media and making wisecracks in interviews. This latest entry in the feud is a classic.

It's certainly amusing to see two of the biggest names on the PGA Tour beefing. It adds a fun element of drama to the proceedings, especially since it's mostly harmless stuff.

Bryson DeChambeau is known as an extremely colorful character with an ability to hit the long ball (sounds like Happy Gilmore), while Brooks Koepka has won four majors since 2017 and is considered by many to be the best player on the PGA Tour when healthy.

Koepka was in position to win the PGA Championship this past weekend, but he faltered on Sunday, helping Phil Mickelson pull off an incredible victory at 50 years old.
