I guess I’m sorta kinda wondering why Humphrey Bogart, Clark Gable, Gary Cooper, Cary Grant, John Wayne, James Cagney…why did we never hear about these guys occasionally bitch-slapping each other during the Oscar ceremonies of the ‘30s, ‘40s and ‘50s?

Probably because their testosterone levels were too low, I’m guessing. They resultantly lacked sufficient manliness — unlike Will Smith, they simply didn’t have the nerve to occasionally throw down and “straighten” each other out.
