If there's one WWE superstar that Vince McMahon should be indebted to over the years, it's the Undertaker.

During the then-World Wrestling Federation's Monday night wars with World Championship Wrestling, McMahon watched several main-attraction superstars bolt from his company to happily accept the big bucks that Ted Turner was shelling out to pro-wrestlers at the rival promotion.

However, the Undertaker never budged, continuing to be a cornerstone and pillar of WWE — for 25 years and counting now.

While McMahon started giving the Undertaker praise on Monday Night Raw last night, calling him "the most-cold-hearted, destructive force in the history of WWE," things quickly took a turn when the Dead Man showed up live in the ring and Vincent Kennedy crossed the line.

After his traditional chilling entrance, the Phenom stood face-to-face with McMahon in the ring, while being showered with chants of "Undertaker, Undertaker!"

That's when McMahon chimed in and said, "That's right ... he's the Undertaker. He's my force of destruction. He does what ..."

Just then, the Undertaker had clearly had enough, choking the WWE owner, before issuing a severe caveat.

"You know ... you know ... you know what's going to happen when I close that door behind me at WrestleMania," the Undertaker said in reference to his Hell in a Cell match with McMahon's son, Shane McMahon, on "the Grandest Stage of Them All" on April 3. "You know what I do.

"The blood of your son is going to be on your hands ... not mine," he grimly said, before walking out the ring.

Still gasping for air, McMahon — as twisted as it sounds — agreed with the Undertaker, saying he has no doubt that he'll be standing in the ring the night after WrestleMania 32, realizing that Shane "has failed to defeat the Undertaker" and that "he has failed me as a son."

McMahon went on to looking forward to Shane losing his inheritance, writing him out of his will and giving all his money to his sister, Stephanie.

He went as far as to state, "I will renounce Shane McMahon as my son" and that Shane-O-Mac will only be an "S.O.B."

Business will continue to pick up next Monday night on Raw, where Shane is slated to be present.

The road to WrestleMania is really gaining steam now.
