The Royal Rumble is chock full of shockers every year.
In 2012, the Royal Rumble match featured the surprise returns of Road Dogg, "Hacksaw" Jim Duggan and Mick Foley. In 2011, we were treated to the returns of Booker T and Diesel.
In 2013, we're bound to get at least a few surprise entrants in the Royal Rumble, which is widely considered to be one of the WWE's biggest matches of the year.
