Elizabeth Rowin got the idea from a comedian, who joked that one way to anger President Donald Trump would be to rename the street in front of his signature property after his Oval Office predecessor.

So Rowin wrote up a petition and posted it to MoveOn.org, the liberal landing place for political gripes and calls to action, she told Newsweek in an interview.

"We request the stretch of Fifth Avenue between 56th and 57th Streets be renamed 'President Barack H. Obama Avenue,'" read her request, addressed to New York Mayor Bill de Blasio and the city council. "Any addresses on that stretch of Fifth Avenue should be changed accordingly."

That stretch includes Trump Tower, which would make Trump's address there 725 President Barack H. Obama Ave.

"I honestly started it as a joke," Rowin told Newsweek.

But as of Thursday morning, more than 250,000 people have signed on.
