Props to the wig designer.

Jimmy Fallon did his best Trump impression with the actual Trump on the other side of the mirror on The Tonight Show. "Trump" interviewed Trump, and naturally, hilarity ensued. Jimmy did ask him some legitimate policy questions, to which Trump replied with vague answers. When asked specifically how he would create jobs, Trump said by "by doing it, it just happens." Trump then tossed the question regarding a wall with Mexico back to Jimmy, and Jimmy said that he'd challenge Mexico to a giant game of Jenga and quit once it was all set up.
