All these shows are organized by event managers etc, script writers and all the script and dialogue is already written. The actors merely perform their roles. thats what even karan johar or others were doing. nothing is impromptu. People are very quick to pass judgment (especially when the topic is of Shahrukh, people forget everything else and open their mouths without thinking.)SRK does not grin when others joke about his stammering or spreading of hands. i have seen that in many award shows and he is cool enough to enjoy gags on himself. recently someone accused of not overacting : he said take SRK if you need overacting. and SRK was found enjoying that comment. SRK is in such a position now , that any hatred is not going to affect him.

Srk and sak are paid to make the jokes...and the subjects get free publicity..
