Jimmy Fallon Plays Beto O'Rourke, Bernie Sanders and Donald Trump in "You Need to Calm Down" Parody

In 'The Tonight Show' parody, Fallon embodied the politicians during the Democratic debates, set to the tune of Taylor Swift's latest song.

Jimmy Fallon gave Taylor Swift's pride-inspired song "You Need to Calm Down" a political twist on Thursday's episode of The Tonight Show.

The parody opened with Fallon sitting in front of a mirror in his dressing room. The host put on a wig that resembled Beto O'Rourke's hair as the tune began to play.

"Hola, mi amigos. I am Beto/Always look like I drank 10 espressos/And people are like, 'Damn, why is he moving his hands?'" sang Fallon as he animatedly spoke with his hands. He continued to sing: "I'm gonna beat Trump/I can't calm down."

After Fallon realized that O'Rourke's numbers were down, he took off the wig and put on a white one with a receding hairline and glasses to embody Bernie Sanders.

As Sanders, Fallon spoke about how he had not changed since the 2016 election. "If you think that I changed, do not worry/Want free healthcare and a comb for my hair," he said loudly. Then: "They say I'm too loud/But I am upset about college debt/So yes, I am loud."

Then Fallon took off the glasses and replaced his wig with a blond one. He happily stared at the mirror as he got into character as Donald Trump.

"Can't believe I stayed up for the debates/Just to watch 20 losers and lightweights/When we all know it'll be sleepy Joe," he said. "I want to tweet now/I keep getting blocked, but I'm loaded and I'm cocked/I'm gonna tweet now."

Fallon then hunched over his phone to compose a tweet before a Tonight Show staff member interrupted the parody to warn him that the live show was about to begin.

The host concluded the parody as himself. "We've got a great crowd/From NYC, Studio 6B," he sang as the dressing room walls tore apart to reveal the audience behind him.
