Undertaker has had a phenomenal 30-year career in WWE, but he's revealed that four matches stand above the rest as his greatest ever.
The Deadman - whose real name is Mark Calaway - explained that he is 'most proud' of his four consecutive showdowns against Shawn Michaels and Triple H at WrestleMania.
His battle against The Heartbreak Kid in 2009 is renowned as one of the greatest wrestling matches of all time and 12 months later 'Taker retired his opponent.
At WrestleMania 27 and 28, he then defeated Triple H in back-to-back matches.
Speaking during episode three of his 'Last Ride' documentary, Undertaker explained that he's proud of those four bouts and how their storylines played out.
"I've got a lot of moments in my career that I hold very near and dear to my heart and are very special to me with a lot of different guys," he began.
"No disrespect to anybody, but you know, overall what I'm most proud of, as far as matches and storylines and all that, are four matches that I had.
"The two with Shawn [Michaels] and the two with Triple H. The two matches with Shawn... man, I'll put them up against any."
There's no doubt that Undertaker's series against Michaels and Triple H is iconic.
For the man himself to pick these four matches ahead of anything else from his illustrious 30-year WWE career says it all.
It's well documented that the three men may not have always been close away from the ring, but the respect they all have for each other is obvious.
The dynamic of their relationship is explored in chapter three of 'Undertaker: The Last Ride' and that will air this Sunday on the WWE Network.
