What a psychologically fascinating little situation. Did he originally genuinely think the joke was funny, or was he just kind of on audience-member autopilot only realizing moments later exactly what he was laughing at? Or was the look on her face enough to turn his reaction 180 degrees?
I could be wrong, but I get the impression that he wouldn’t have behaved that way naturally, but rather that something either internally or externally was influencing him to take up the chivalrous knight defending ye fair maiden’s honor role.
Thought his little speech was a good example of how years and years of extreme fame and adulation can eventually warp a person’s personality. How could it not? I’d imagine that if I had the amount of fame and success in my life as Will Smith, I’d probably be poisoned by celebrity as well.
