It was Republican Presidential candidate Carly Fiorina that kept Donald Trump on his toes at last night's (September 16) GOP debate at the Ronald Reagan Presidential Library — but a little bit later, Democratic candidate Hillary Clinton made sure she got in a few jabs, too.

In a Tonight Show sketch that found Jimmy Fallon dressed in head-to-toe Trump garb (toupee and strange, patchy spray-tan included), the comedian challenged the politician to clarify her views on campaign strategies, immigration policy and—what seems to be Trump's favorite topic—women.

"What would you do to help women in this country?" he presses Clinton in a mock-phone interview in the clip above.

"I've spent my entire career fighting for women's rights," Clinton fires back to applause. "That's what I believe in. That's what I'm fighting for...What is your stance on women's issues?"

"Look, I know a lot of women, and they all have issues," he answers.

And though a final contest might come down to Clinton and Trump, the faux-politician benevolently offers some advice.

"You wanna win? Here's what you gotta do. First: yell," he instructs. "I yell all the time. In fact, this phone isn't even plugged in, I'm just yelling."

Finally, he wraps up the talk with Trump's signature humility.

"Anyway, you're welcome for this interview, I just really helped your campaign," he says. "Your poll numbers are gonna be fantastic; they're gonna be big--"

"Don't you mean they're gonna be huge?" Clinton jokes.
