Stewart was shocked Trump is still running his campaign: "That angry tax- and draft-dodging little orange groundhog is running for President?”

On Election Eve, Jon Stewart stopped by The Late Show to join his old friend and former colleague Stephen Colbert to urge voters to do their civic duty Tuesday.

The night before his Showtime election night special, Colbert took the stage on his live Late Show to first talk about Donald Trump’s team taking away his Twitter account. “That’s like taking away Batman’s utility belt. All you’re left with is a billionaire with anger issues," said Colbert. "He’s got none of his tools!”

After a “ragamuffin” little girl interrupted Colbert’s monologue with her sad story about being too scared to vote, the two of them broke into a musical number about how important and easy it is to cast a ballot, even though she was somewhat jaded by the whole process.

But before Colbert could convince her to vote, Stewart appeared (in a red top hat and “Jon Stewart" sash) to give the audience “toffee from an old man’s pants” and to tell the audience, through song, they don’t really have to vote. He sang his opinion, until Colbert interrupted to ask him if he remembers who is running for President this year.

“I assume Walter Mondale, that nice Mormon fellow perhaps?” Stewart guessed.

He took a quick sip of water while Colbert broke the news that it’s Donald Trump, so while Colbert wiped his face dry, Stewart asked him to tell him just one more time, but Stewart still didn’t believe it: "That angry tax- and draft-dodging little orange groundhog is running for President?”

Just when Colbert and Stewart were beginning to lose faith in the election, Hamilton's Javier Munoz appeared to remind them how important voting is, because, taking a line from the Hamilton tune, "history has its eyes on you."

In a plea to vote, Munoz sang to "please tell me you're not throwing away your shot" before he had to run back to Broadway.

Stewart and Colbert were joined by a choir to finish off the musical number, which Stewart concluded about Trump: "You know he acts tough but he's a wussy. He'll probably fill the court with Gary Busey. And then he'll grab your mother's --" But Colbert interrupted him before he could finish the rhyme. The episode also featured an appearance from Stevie Wonder, who played a bit of "My Cherie Amour," Love's in Need of Love Today" and "Don't You Worry 'bout a Thing" as he made an impassioned plea in support of Democrat Hillary Clinton. "Don't believe those who say to you your vote doesn't matter. Because your vote does matter."
