Butterbean scored one of the most brutal knockouts of his career against Louis Monaco in December 1995.

At the time, the popular American puncher was undefeated at 14-0 and was being guided by Hall of Fame promoter Bob Arum.

Butterbean - real name Eric Esch - was at a career-lightest 300lbs for the bout.

While that may seem extremely heavy to most, by Esch's standards it was very trim.

The loveable heavyweight icon ballooned up to as heavy as 430lbs during his 91-fight (77-10-4) pro boxing career.

But for his showdown with Monaco, Esch had dropped 15lbs from his last outing with Pat Jackson.

That fight, which had taken place two months prior, saw Butterbean accidentally knock down referee Terry Wood at the end of the third round after he tried to separate the fighters at the bell.

Luckily for the third man in the ring during Butterbean's next fight - Lou Filippo - the contest didn't get past the first stanza.

It took Butterbean just one minute and 58 seconds to dispatch Monaco, although it could have come a lot sooner.

Monaco was on the floor in the opening three seconds after Esch came charging across the ring and decked him with the first shot he threw - a crisp right hand.

After dusting himself off, the musclebound boxer made the unwise decision to fight fire with fire and was knocked down once again less than 30 seconds later.

As Monaco made his way back to his feet for a second time, Esch walked his adversary down and closed the show with a picture-perfect overhand right.

The vicious shot left Monaco lying motionless underneath the bottom rope in one of the scarier stoppages of Butterbean's career.

It marked Esch's fifteenth straight victory and his last one as an undefeated fighter as the Atlanta banger met his match against Mitchell Rose two weeks later.

Rose - who retired with a 2-11-1 record but was 1-7-1 at the time - became the first man to beat Esch when he stopped the big man in the second round of their clash on the Jesse James Leija vs Oscar De La Hoya undercard at New York's Madison Square Garden.

Esch continued knocking over carefully picked opponents for the rest of his 19-year tenure in the paid ranks, losing almost every time he stepped up in level.

Butterbean eventually hung up his gloves in 2013 after getting stopped by Kirk Lawton.

However, the now-57-year-old continues to tease a boxing comeback to this day.
