Jason Dunstall joined JB and Billy on Triple M's Rush Hour - and with a bit of a score to settle.
JB's taken a few pot shots at Chief recently, on Instagram, about all the monkeys - Chief's descendants - floating around during his holiday in Bali a few weeks ago.
So it took a few minutes for Chief to even officially acknowledge the presence of JB...but once he did, all bets were off.
"Chief! We go back a long way!"
"NOT FAR ENOUGH WITH THE SHIT YOU'VE BEEN CARRYING ON WITH!"
"YOU ARE DEAD TO ME BOY!"
