Arnold would convince Ronnie that he is pregnant, and have him running to the hosiptal to give delivery. Then he would tell Sergio that he overheard something about green cards. Next he would get Dorian to believe there is free fish and chips in the lobby. He would be the only one left, and he would win first place.
All jokes aside, you can't tell from some pics. Arnold had an awesome body, and I love him, but even I will admit todays guys are bigger (but thats not always better!). But, Arnold did have a way with mind fucking people, and had a charisma on stage. So, my money would be on Arnie. But you never know, and never will.
