The "Slap Heard Around The World" as it is being called was truly a bizarre event. Many people figure it must have been some kind of publicity stunt since that is the explanation which makes the most sense. Otherwise it would seem that Will Smith is psychologically unstable and unable to take a mild and harmless joke. Additionally, under normal circumstances someone who disrupts a public event, as did Will Smith, would be ejected, and so it's reasonable to be suspicious about this incident which has been widely discussed and scrutinized. Alopecia areata (aka, AA or patchy hair loss) is an unfortunate and potentially embarrassing condition and it is not nice to belittle someone suffering from the condition. However, Chris Rock's joke did not belittle Jada Pinkett Smith in any way. It was just light teasing at most and a cute joke in general. Besides that, if she were to make a cameo appearance in a GI Jane sequel, she might make a little extra money, not that she or her husband need it.
