Not everyone in Karachi want him!! so is it in Punjab and other province that they dont like many of the MNA or MPA or etc as they want someone else to be at that position.
Also laughing at someone is a personal thing. Media also make a lot of funny sketches and funny clips regarding politicians. So you think people should cry on it, while watching them doing funny things around?
Also saying from my side. I dont think so that there is any kind of normality in what this person speak or even from his speaking style.. so its kinda funny to hear it.
