Donald Trump didn't ruffle too many feathers during his interview on "The Tonight Show" on Friday, his first late-night appearance since announcing his run for president.

Jimmy Fallon conducted a lengthy but consequence-free interview with the Republican frontrunner, who continues to dominate the GOP field with his off-the-cuff campaign style.

In a speed interview, the two discussed the serious subjects of Hillary Clinton's email fiasco and how he plans to build a wall along the Mexican border. Trump also talked about taking better care of U.S. veterans, said something nice about his opponent Carly Fiorina and weighed in on Kanye West's announcement to run for president in 2020.

Trump also sat down with the only man qualified to interview him - himself (or Fallon dressed as Trump). He admitted he's always ready for the debates and that he's "just going to do it" when it comes to creating jobs. Trump than asked himself (Fallon) how their going to convince Mexico to build that border wall.

"How am I going to get Mexico to build a wall? Easy. I'll challenge them to the biggest game of Jenga ever," he suggested. "I'll make them set up the board. And then when they finish I'll say, 'I don't want to play anymore.'"

Trump will next appear on Fallon's late-night competition "The Late Show with Stephen Colbert" on Tuesday, Sept. 22.
