Stephen Colbert speaks with Tim Walz and John Oliver ahead of the election

Stephen Colbert traveled to Philadelphia on the eve of his election Late show Interview with Tim Walz, in which the high school football coach and future vice presidential candidate gave America one final pep talk before Tuesday.

“Governor. “Walz couldn't come to the Ed Sullivan Theater because that building isn't a swing state,” Colbert quipped Monday night, before the show cut to a pre-recorded interview with Kamala Harris' vice president filmed at the Johnson Hall Coffee House in Bucks County , Pennsylvania.

Early in the interview, Colbert asked Walz about his highs and lows on the campaign trail – when the Veep candidate said there were no lows, he said Late show The host asked, “Don’t you even share the stage with JD Vance?”

“Okay, that wasn’t great,” Walz admitted.

(The highlights? “I see my former students,” Walz said. “A lot of them are coming back… I'll see them at events everywhere.”)

Walz's 10-minute softball interview covered the story of how he met his wife Gwen, his affinity for Diet Mountain Dew and the Midwest's best insults – “I'm not mad at you, I'm mad at your behavior.” That Duo also played a game of paper football.

When asked if he was surprised by the indecisive polls, Walz said no. “It disappoints me because I think the choice is so stark,” he said. “But it’s not surprising, the country is really divided.”

He then explained the concept of an opportunity economy using the language of auto repair, at Colbert's request.

“So your car is running a little rough, it's still running, but there are things you can do,” Walz said. “And now, if it’s an older vehicle, you can have the carburetor cleaned. You can invest the money in a really important part, for example the carburettor, in the middle class. You have invested a little in this carburetor. The entire vehicle runs better. This allows oxygen to enter the entire system. So you invest in the middle class…the middle class makes everything else work.”

The segment ended with Walz's pep talk. “We know we are in the last two minutes of this game,” he said. “We will give 110 percent, we know that we have to leave it on the field because democracy is at stake here.”

Last week tonight Host John Oliver joined Colbert after Walz, where the two comedians discussed their experiences covering Donald Trump for nearly a decade.

“2016 came and never left,” Colbert said. “We’re now eight years into the 2016 news cycle.”

Colbert also played in 2015 Late show Clip of Oliver saying he “doesn’t care” about Donald Trump announcing his first presidential run. “Wouldn’t it be great to go back to a time like that?” Colbert said Monday.

Oliver agreed, saying: “I still don't give anything from him, I just have to do it.” I just want to be in a situation where I don't have to worry about it anymore. So I go back to my original state, which is that this guy means nothing. That’s what I want so badly.”

Elsewhere in the interview, Colbert asked Oliver about Elon Musk's one-sided feud with the Last week tonight Comedian.

“I think one of the things is that he clearly loves comedy,” Oliver said of the billionaire Trump supporter, who frequently stalks Oliver online. “So he wants to be funny. And unfortunately, money can't buy that – he'll never be funny that deep down, and it must be eating him alive because he's trying so hard to be funny. And every time he tries it, it has to seem like it's further away from him, that laugh he's always chasing but will never catch. And that will be a vacuum at the center of his soul for a long time.”
