Undertaker on his retirement
Speaking on 'The Bill Simmons Podcast', Taker talked about his retirement: "I know I have more matches behind me than I do in front of me," Taker mentioned.
"So people would tell me 'Dude you need to get yourself out there because this wrestling career is coming to an end, now it's time to cash in on the brand and the stuff you didn't do for all these years post-WWE'
One of the first things I did out of character was I posted about the Longhorns winning the Sugar bowl, I'm scrolling through comments and I see 'My childhood is ruined, The Undertaker is now on social media'
You've got to be s--tting me. People were genuinely pissed I broke character after 30 years." The Deadman discussed how his fans can be loyal to a fault. He noted that some fans hate his wife, Michelle McCool, simply for being married to him.
"People hate Michelle cause she's married to me," Taker added. "People didn't want to see that, all they wanted was what I gave them or more. My fan base has been very loyal especially when you consider how long I've been here like my fan base has stayed with me and obviously they've had children now.
But they're very possessive and protective of The Undertaker." Widely regarded as one of the greatest professional wrestlers of all time, The Undertaker is a seven-time world heavyweight champion in WWF/E, having held the WWF/E Championship four times and World Heavyweight Championship three times.
