Josh Koscheck pulled the earbud out of one ear, but continued his brisk walk to the stage before his weigh-in at UFC 74 in August 2007.
It was the first time the irreverent welterweight faced Georges St. Pierre -- then known more for his striking and athleticism than his now-trademark ground control.
St. Pierre entered the fight as the fan favourite -- winning them over with his broken-English please and thank-yous.
Koscheck came in with a mission to expose St. Pierre as a phony.
"I think Georges St. Pierre is a fake," said Koscheck about St. Pierre's squeaky-clean image back in the summer of 2007. Koscheck went on to lose a unanimous decision to the Montrealer the next night.
The two will meet again in a welterweight title fight at UFC 124 on Dec. 11 in champion St. Pierre's hometown following their stints as coaches on The Ultimate Fighter 12.
In speaking with the media earlier this week to hype the premiere of TUF 12, Koscheck's earbuds were nowhere to be seen. But the tune hadn't changed one bit.
"Just from being around him, I really, truly believe that he portrays to be this guy that I think he's definitely not," says Koscheck, who's 15-4 and riding a three-fight win streak.
"So he comes across, you know, different than what he is in-person."
St. Pierre says there's nothing fake about his persona.
"It's a lie that I'm a fake person, and as you're going to see on the TUF 12 show, that is not true at all," says St. Pierre (20-2). "I never derail from the personality that I am and from what I stand for."
Koscheck makes no excuses for his loss to St. Pierre at UFC 74, but says he has improved as a fighter since then -- and St. Pierre hasn't.
"Since GSP got knocked out by little Matt Serra (at UFC 69 in April 2007), he's become this guy who's afraid to go out there and fight," says Koscheck, who calls St. Pierre's style boring.
"He's hired Freddie Roach as a boxing coach, and, to be honest with you, Georges, I think you're wasting your money and wasting your time. Because you know that you're not going to come out there and stand up with me."
The 32-year-old Koscheck says he enjoyed his time coaching lightweight fighters against St. Pierre for TUF 12.
He also says he took the opportunity to get into St. Pierre's head.
"I definitely know that I got under Georges' skin, you know, and he's even admitted it in his interviews," says Koscheck.
"And I kind of like that. I like the fact that now Georges is pissed off. I like the fact that he's training hard, because when I whip his ass on December 11th, then he's not going to have any excuses."
