There appears to be no end to recent rival billionaire trolling of Republican presidential nominee Donald Trump.

Over the weekend, rival reality show star and billionaire Mark Cuban endorsed Hillary Clinton while calling Trump a "jagoff," a Pittsburgh derogatory term for, well, a jagoff.

On Monday, the Shark Tank star revealed he will be a judge of Miss America, the rival pageant to Trump's Miss U.S.A.

Miss America, of course, takes place in Atlantic City -- the Democratic Party's favorite backdrop for anti-Trump sentiment and the site of a Hillary Clinton rally last month. Recent ads have targeted Trump's serial bankruptcies, de-Trumped hulking buildings that used to be his casinos and other remnants of his arguably failed casino empire by the sea.

Another rival billionaire, New Yorker Michael Bloomberg, spoke at the recent Democratic National Convention in Philadelphia and appeared to question whether Trump was sane. [UPDATE: Monday afternoon, another billionaire Warren Buffett, got into the troll Trump game, appearing in Omaha, Nebraska, with Clinton and vowing to drive voters personally to the polls. He also challenged Trump to a release-your-taxes billionaire duel.]

Cuban, who takes great pains to tell people that his Shark Tank reality-TV juggernaut "kicked The Apprentice's [behind]," will be one of the celebrity judges who name a new Miss America on Sept. 11 in Atlantic City.

Judges typically will attend a press conference in the week leading up to the pageant, which will give Cuban, the owner of the Dallas Mavericks, another platform, this one in Atlantic City, to take on Trump, if he chooses.

Also named as judges Monday were actress Sara Foster, singer Cole Swindell, and Sharlene Wells Hawkes, Miss America 1985.
