It's been 29 years since The Undertaker debuted for WWE, and he's endured a career like no other superstar in the history of the professional wrestling business.

He has reinvented himself time and time again over the years, and Undertaker is a seven-time World Champion. It's no wonder that Vince McMahon has called The Phenom is favorite wrestler.

Prior to joining WWE, Undertaker had a brief stint in WCW, where he performed as "Mean" Mark Callous. When that didn't work out, he received an offer from WWE, and the company's history changed forever.

But like many of the all-time greats, Undertaker didn't get off to the greatest start when he met with WWE.

The Deadman has been detailing his career on The Broken Skull Sessions. This time, Undertaker talked about one of his first meetings with Vince McMahon and WWE, and it simply didn't go so well:

"So we get to the end of the meeting and it’s like ‘Well, we don’t really have anything for you right now’ I wasn’t expecting that. I had already given my notice. You know, I’m done, I’m done with WCW at this point that was it.

I was like, ‘Wow I didn’t plan on that happening.’ I was already told by one company that nobody would pay money to see me and now this guy doesn’t have a spot for me — maybe after Mania and we’re talking months and months away.

So I’m trying to stay positive. I know I’ve got it in me somewhere to make it somewhere, but it was shaky there for a minute."

Well, it didn't take long for Undertaker to make an impact in WWE. He dominated and crushed his opponents in the early going, and he entered feuds with some of the company's top superstars, including Hulk Hogan and Jake "The Snake" Roberts.

Undertaker especially became more critical to the WWE during the Attitude Era, when the company was engaged in the Monday Night Wars with WCW. His storyline with Kane, as well as the Ministry of Darkness stable, were complete game-changers during the wars.

Here we are almost 30 years later, and Undertaker remains perhaps the greatest superstar in WWE history. Even at the age of 54, he's still going strong - and he doesn't seem intent on retiring any time soon.

Signing Undertaker May Have Been Vince's Best Decision 

Vince McMahon has made plenty of excellent business decisions that led to him becoming a billionaire. But signing Undertaker may have been the greatest move in Vince's time as the WWE chairman, seeing how The Deadman has been a top money draw for three decades and counting - and the fact that they managed to get past WCW despite being on the verge of losing the wars.
