5: Mr. Wrestling II
One of the most athletic men to ever compete, Mr. Wrestling II was once called 'rubberman' because of his extreme flexibility.
While most wrestling fans are well versed in his vicious knee lift finisher, not many know that Mr. Wrestling literally put his body and career on the line to protect the sport he loved.
Mr. Wrestling was in the famous plane crash that broke Ric Flair's back. Since the passenger manifest was a matter of public record, many speculated that Tim Woods was the man behind Mr. Wrestling II's mask.
This was the 1970s, and kayfabe was alive and well. The prevailing opinion among wrestling promoters and the wrestlers themselves was that if it were ever revealed that sports entertainment was scripted, the business would suffer. This atttutide extended to things like heels not hanging out with babyfaces, and the identity of masked wrestlers.
In order to protect kayfabe and the wrestling community, Mr. Wrestling II climbed into a ring just two weeks after the plan crash, to 'prove' that Tim Woods and Mr. Wrestling II could not be the same person! If that's not tough, we don't know what is!
