I've been thinking this for awhile now too, cause Shane has been involved in a number of big show related things. First with the fatal 4 way stuff at WM2000, and then we also saw Shane being involved in the Big Show-Mayweather stuff as well, maybe they managed to convince him to come back for this one last huge McMahon family rivalry?Big Show with Shane again? Hmm.
I don't think there's ever been a no contest with a special ref involved either.
