Sami could wear a costume and come in like he was a fan. For the whole show he's just cheering and booing with the fans. Davey comes out and says Sami was too scared to wrestle him(or something to that effect). Then all of a sudden(Sami is on the other side of the ring behind him while this is going on btw) he gets up, rushes the ring and whoops Daveys ass. He rips off the mask, goes to the top turn buckle to soak in the boos(or cheers
) then the bell rings.
