Saracens have given supporters the chance to watch them take on Sale Sharks for free on November 30 if they arrive for the clash dressed up as Elvis Presley.
The club have come up with the idea to mark the 37th anniversary of the late pop star's concert in Anaheim.
As part of the celebrations, tribute acts and a lookalike contest will take place during the day, according to the Daily Mail.
The idea has come about following the club's offer of a refund if Gavin Henson scored a point against them back in September, but he failed to do so.
