Angle and Lesnar collided at the main event of WrestleMania in 2003 at Safeco Field in Seattle, Washington for the WWE Championship.
Towards the end of the match The Beast tried to hit the then champion with a Shooting Star Press but the high-risk move went wrong and he landed on his head.
The Conqueror, however, still managed to get up and hit the 1996 Olympic Gold Medalist with another F5 to win the WWE Championship.
The botched move caused Lesnar a concussion that kept him out of action for a few weeks.
Angle claims he was the one who advised his opponent to finish the match with that high-flying move but remembers the incident as one of the scariest moments of his career.
The six-time world champion said during a Facebook Q&A: “Well, it was my idea to do the shooting star…
“Brock misjudged the flip and landed on his head. It was a scary moment.
“But nothing was said between us about it. The match spoke for itself regardless of the failed flip.
“If anything, it became one of the most popular WrestleMania moments.”
Lesnar and Angle went on to have some more incredible bouts against each other at SummerSlam and Vengeance.
The Beast also beat The Olympic Hero in an unforgettable 60-Minute Iron Man Match on Smackdown.
The Conqueror left WWE a year after his unforgettable botch and joined UFC in 2008 where he thrived and beat Randy Couture for the UFC Heavyweight Championship.
Lesnar returned to WWE in 2012 and dominated the competition as he won two more world titles and became the longest-reigning Universal Champion of all time.
The UFC legend destroyed some of WWE’s biggest legends like John Cena, Triple H as well as CM Punk and also ended The Undertaker’s undefeated streak at WrestleMania.
His last match took place at SummerSlam where his 504-day reign as Universal Champion came to an end by Roman Reigns.
The ex-WWE Champion is set to compete again at WWE Crown Jewel on November 2 at the King Fahd International Stadium in Saudi Arabia where he will take on Reigns and Braun Strowman in a Triple Threat Match for RAW’s premier title.
