I know Pierre and Damian Vachon are not the actual sons of Butcher Vachon. That is just kayfabe.

I guess from personal experience I could add John Hennigan (Johnny Mundo) to this list. When I talked to Hennigan about it at BOLA last year he liked the cards I showed him and verbally said yes when I asked him if we could put him in the game. But when I told him he needed to sign the official release form he politely took it from me and asked for contact info (which I gave him) and then said he would have to ask his agent.
but this game is not about who has said no, it is about who has said yes and I really hope somebody in particular who recently said yes gets a card soon!
