Has anyone Never tapped out?

First topic message reminder :

I've been looking over Youtube videos and reading up on it because I was curious if there was any superstar past or present that hasnt tapped out at one point or another.

Takers done it, Angles done it, Cenas done it. Even Hulk Hogans tapped out.

Orton, HHH, HBK, Kane, Big Show, Benoit, The Rock, Stone Cold, CM Punk, ADR, Christian, Edge, Lesnar, Khali, Jericho, Mysterio, Rhodes, Ziggler, Barrett, Bryan the list goes on.

So, has anyone never tapped out in their Career? Im struggling to find anyone.

I think Zack did as part of the Edgeheads, maybe to Taker?

Zack Ryder has lost to Alberto Del Rio recently so i'd assume that was by submission?

Rikishi?

Sorry lads, that was me attempting sarcasm. Ryder taps like a b!tch every time I see him lol!!

Taz??

As far as I'm aware, Mick Foley never tapped in any of his personas. He lost an I Quit Match but that was revealed to be a screwy finish shortly afterwards.
