The final SNL of 2019 features a cold open that takes on the most recent Democratic debate for the 2020 presidential election.

The field of 2020 Democrats included Jason Sudeikis, who previously played Joe Biden, Larry David as Bernie Sanders, and a surprise appearance by Kamala Harris, played by Maya Rudolph. Later, Alec Baldwin’s Donald Trump came on stage to remind everyone that he won't get impeached, and then went head-to-head with Kate McKinnon’s Nancy Pelosi. You can watch a clip of it here.

Last weekend, SNL tackled the impeachment proceedings by centering it on three families who have different viewpoints on the issue. The skit featured a liberal family in San Francisco, a conservative family in Charleston, and a black family in Atlanta.

Near the end, Aidy Bryant, playing a snowman narrator, noted that the families are actually quite alike. “They have one important thing in common,” she says. “They live in states where their votes don’t matter, because none of them live in the three states that will decide our election.”

That’s when Kate McKinnon interrupts Bryant, playing Greta Thunberg, who is the 16-year-old climate activist mocked by President Trump for being on TIME’s Person of the Year.

“The ice caps will melt, and the elves will drown,” she said. “So Merry maybe our last Christmas to all, and Donald Trump, step to me and I’ll come at you like a plastic straw comes at a turtle. I can’t believe I’m saying this to a 70-year-old man, but grow up.”

Tonight’s SNL is hosted by Eddie Murphy with musical guest Lizzo. In promos for the episode, Lizzo is hilarious as she shares her excitement about Murphy’s return to Studio 8H. You can watch it below.
