There are many reasons why most fans consider the Royal Rumble to be one of the most exciting pay-per-views of the year, but there is no question that the ever-present possibility of surprise entrants is one of the biggest.
While the idea of the surprise entrant is a fairly new phenomenon that has picked up steam over the past decade or so, it is one of the biggest topics of conversation ahead of every Rumble match. In fact, it has gotten to the point where fans are disappointed if there aren't at least a couple good surprises per year.
