Rudy Giuliani has been well and truly pranked, and by the master scamp of the “Borat” gotcha movies, Sacha Baron Cohen. And there’s precious little he can do about it in the courts of law or public relations, say lawyers and crisis experts.

Sure, he can bellow on Twitter against Baron Cohen, calling him a liar while trying to explain what he was doing flat on his back on a hotel bed with his hands down his pants (he says he was tucking in his shirt) and a young “reporter” by his side, in a scene from Baron Cohen’s latest, “Borat 2,” streaming now on Amazon Prime.

But so far Giuliani, 76, 77, has not hired a new lawyer to help him take Baron Cohen to court to block the film (full name: “Borat Subsequent Moviefilm: Delivery of Prodigious Bribe to American Regime for Make Benefit Once Glorious Nation of Kazakhstan”) or to sue for libel, defamation or just the general monkey business for which Baron Cohen has become notorious.
