Larry David as Bernie Sanders on "Saturday Night Live."

Who is the curmudgeonly actor who keeps nailing it on "Saturday Night Live" with his Bernie Sanders impersonations?

That would be the same man who heckled Donald Trump on Saturday and called him a racist: Larry David.

David made headlines when he shouted, "Trump's a racist!" during Trump's monologue on Saturday. Trump was onstage with two impersonators as he opened his hosting gig.

"Who the hell is -- I knew this was going to happen," Trump said, before the camera showed that the heckler was David, who is "Saturday Night Live's" go-to Sanders stand-in. This time, though, David (co-creator of "Seinfeld" and star of HBO's "Curb Your Enthusiasm") dressed as himself.

The Latino advocacy group Deport Racism offered anyone who heckled Trump during his monologue and said "Trump is a racist" would receive $5,000 from the group. David did just that, shouting, "Trump's a racist," and then saying, "I heard if I yelled that, they'd give me $5,000."

The heckling appeared to be a setup that didn't seem to bother Trump too much, but Deport Racism is still happy to hand over $5,000 to everyone's favorite Bernie Sanders impersonator. They said he has yet to collect the bounty, but if he doesn't, they may re-offer the prize to anyone who heckles Trump during the next GOP debate in December, reports CNN. Watch the next Democratic debate, Saturday, November 14th on CBS.
