In a video preview to promote the debut of FUEL TV's "Fighter's Cut" tonight at 10 p.m. ET, Mir mocks the fellow former UFC champion's signature sword tattoo across his torso, as well as a specific part of his physique (transcription via MMA Mania).
"He flexed and I said, 'Man, you see how big his back is?' To see a guy who's 6'4" and that thick, and long muscles on top of that, athletically moving, I was impressed. It's funny how things hit you. I was like, 'I know why he got the tattoo! It was to take everybody's mind off the fact that he has boobs.' You know they kind of hang, when he jumps, they bounce up and down. So I thought, 'Oh, it's a diversion. Look at my dumb tattoo so you can keep your mind off my very feminine chest muscles.'"
Of course, Mir has no lost love for the two-time All-American collegiate wrestler, as they battled twice inside the cage during Lesnar's brief eight-fight career.
Mir, a highly regarded Brazilian Jiu-Jitsu black belt, locked up a kneebar against his hulking adversary at UFC 81 in Feb., 2008. This was voted the Submission of the Year by FIGHT! Magazine.
However, the rematch at UFC 100 in July 2009 went much differently, as Lesnar once again got Mir down to the mat with ease, but was relentless with vicious ground-and-pound.
This earned Lesnar the unified UFC heavyweight title, which he successfully defended against Shane Carwin before losing the belt in his next fight to Cain Velasquez at UFC 121 in Oct. 2010.
After a second bout with the intestinal disease diverticulitis, Lesnar tried to scrap inside the Octagon one more time against Alistair Overeem.
Suffering a TKO loss in the first round, the South Dakota native immediately announced his retirement from the sport and has since returned to the WWE on a limited basis.
Mir has gone on the record saying he has "legitimate hate" for Lesnar and once even said he'd like to see the Death Clutch gym co-founder die in the Octagon.
