#2 Mick Foley
One of the most popular wrestlers of all time, Mick Foley needs no introduction. I grew up watching Foley in his Mankind persona and have been a fan ever since. However, one thing I didn't know was that Foley's original WWF debut came in 1986. Yeah, that's a long time ago.
Foley made his WWF debut on an episode of Superstars in 1986. He teamed up with Les Thornton in a losing effort against The British Bulldogs. Interestingly, Mick Foley wrestled under the name Jack Foley that night.
#1 CM Punk
CM Punk was a massive star in WWE before he left the company abruptly in 2014. He went on to have an unsuccessful UFC run before returning as part of WWE Backstage.
CM Punk's televised WWF debut came on an episode of Sunday Night Heat in 2005 where he teamed up with Russell Simon to face Maven and Simon Dean.
Punk and Simon were squashed in around 2 minutes. Maven picked up the win for his team after pinning Russel Simon.
