Now everyone knows sibling rivalries can be strong. When sisters want to fight, sometimes you have to just let them go at it. But not when they’re on a raft going down class IV rapids. 

It was during a trip down the lower Nanatahala River Gorge in North Carolina that two sisters decided it would be perfect time to settle their sibling differences. And what do you know? They were reportedly drunk.

With the pair punching and pulling each other’s hair, they try pushing one another off the raft as it rushes down class IV rapids. 

“Stop it!” their guide screams, trying to tear the two apart as the raft spins downriver. 

Luckily for us, passing kayakers — one with a GoPro attached to his camera — caught the action on video. Enjoy!
