When they were younger, there was lots of competition in the Barrett household.
Now as All Blacks themselves, Beauden, Scott and Jordie are the ones being argued over.
A video posted to Facebook shows siblings Jonty and Oscar McLean in a lively debate over which Barrett they are, and it's torn on the heartstrings of many.
It starts with 7-year-old Jonty deciding he is Jordie, while young brother Oscar is Scott, and their baby brother Bodie is Beauden.
But that doesn't sit well with 2-year-old Oscar who fires back, "No, I'm Beauden Barrett."
Jonty bounces back, "No, you're Scott Barrett! Okay?! Got that?! Gosh!"
After a brief pause, Oscar takes a deep breath and concludes, "I'm Beauden Barrett".
The "hilarious" video was posted to Facebook and has been shared more than 1500 times.
Dad Kyle told Stuff the family was "cracking up" while watching the brothers argue.
"I think what most people have connected with is the whole sibling rivalry," he said.
One commenter labelled it "hilarious" while another said it had "made their day".
The Barrett brothers were raised on a farm in Pungarehu - and are the sons of Taranaki and Hurricanes stalwart Kevin "Smiley" Barrett.
Kevin famously said he was going to "breed some All Blacks" when he finished his playing career.
