As mentioned in one of the previous posts on this page, Chaudhry Nisar has this habit of threatening to expose "all that he knows" about the Sharifs but never does.

That teasing of Nisar's has been captured perfectly in this double entendre of a tweet by PTI's Dr Arif Alvi.

It's probably not wise to crack jokes at the expense of someone whom your party is tacitly courting. But maybe Dr Alvi wants to sabotage PTI's attempts to recruit Nisar. Or maybe Alvi's advice would help Nisar finally drop a bombshell.
