GOP presidential candidate Donald Trump has recently been compared to Adolf Hitler, and Sarah Silverman took that comparison literally when she channeled the German Nazi leader during her appearance on "Conan" Thursday night. The always outspoken comedian dressed up as the dictator in full Nazi uniform, including a swastika armband and Hitler's signature mustache.

"I think most people would agree Donald Trump might be the most divisive candidate ever," said host Conan O'Brien while introducing Silverman. "Even as he continues to beat primaries, many are openly comparing Donald Trump to Adolf Hitler. It's pretty common. In fact, New York's Daily News ran this front page earlier this week: 'Trump Is Hitler.' It doesn't get much worse than 'Trump Is Hitler,' so I asked if he would come out tonight to address these comparisons. Shockingly, he's in town. He agreed."

Silverman then walked out onstage in character to "more applause than expected" as she explained why Hitler was not bothered by any of the policies Trump has revealed on the campaign trail.

"I agree with a lot he says - a lot," Silverman as Hitler admitted to O'Brien. "Like 90 percent of what he says, I'm like, 'This guy gets it.' But I just don't like the way he says it. It's crass. What kind of person talks about his penis size on national television? Oh yeah, I'm so sure Donald Trump has a big penis. I famously have a micropenis. That's what makes a tyrant."

"All these comparisons to Trump - it bums me out," Silverman as Hitler continued. "Sometimes I watch him and I'm like, 'Is that how people see me?'"

Silverman is not the first celebrity to speak out against Trump. Last week, comedian Louis C.K. also compared the GOP front-runner to the German dictator.

"Please stop it with voting for [Donald] Trump," C.K. wrote in an email Saturday, March 5. "It was funny for a little while. But the guy is Hitler. And by that I mean that we are being Germany in the '30s. Do you think they saw the s--t coming? Hitler was just some hilarious and refreshing dude with a weird comb over who would say anything at all."
