I wouldnt be intimidated by Oscar if I saw him, He looks like a nice guy. He is more one of those guys that hits on your gf in a club then when you step up to tell him to go away he beats you up badly and ruins your evening.
No, he would not beat you up. He would more likely apologise and walk away. I remember him saying that what he lived by when challenged to fight outside the ring was, "I don't fight for free" I'd say Tyson, Duran
Mike Tyson Roberto Duran Sonny Liston George Foreman Benny Briscoe/Marvin Hagler/Thomas Hearns (take your pick)
This is true. Oscar wrote in his book that street fights are much too dangerous because they have no rules.
