George Foreman could seriously whack and he showed that in his world title clash with Michael Moorer.
The pair went toe-to-toe in 1994 as Foreman made an attempt to become the oldest heavyweight champion of all time at 45 years old.
The two men traded shots for nine rounds and Moorer was up on the judges scorecards coming into the latter stages of the fight.
But, Foreman refused to give up, as he came out swinging in round ten.
And it worked, as he caught Moorer with a thunderous straight right hand that left him lying flat on his back on the canvas.
Moorer attempted to get back to his feet, but all he could do was lift his head and roll over as the referee waved off the bout.

Foreman held onto his heavyweight world title for another year extending his record as oldest heavyweight world champion to 46 years and 169 days old, which is a record that remains to this day.
Foreman went on to have three more fights, winning two and then losing to Shannon Briggs before he retired for the second time in 1997.
This came after he had already previously retired in 1977 having become becoming world champion for the first time in 1973 with an incredible win over Joe Frazier.
But, a year later, Foreman took on Muhammad Ali in 'The Rumble in the Jungle' and was beaten in one of the most famous fights in boxing history.

From here, Foreman never quite got back to the scintillating form that saw him become world champion for the first time and so he hung up his gloves.
But, 'Big George' redeemed himself in the second stint of his career and finished for good with a record of 76-5, with 68 KO's.
