the 60+minute men

There haven't been too many in the history of the royal rumble match, I think there are four or five, they're listed from most recent to earliest:

2006-Rey Mysterio
2006-Triple H
2004-Chris Benoit
1993-Bob Backlund
1992-Ric Flair (Ok, well it wasn't actually an hour, (59:27) unless you count from his buzzer).

And that's it. Four of those five men have won the Royal Rumble before, and three of 'em have won it where they lasted for 60+ minutes.

Backlund holds the record for longest time without ever winning. Trips is 2nd.
