Sen. Bernie Sanders (Vt.) is offering Stephen Colbert some late-night advice, interrupting the “Late Show” host’s monologue to deliver a few wisecracks and tips of his own.

“Folks, how about that New Hampshire last night?” Colbert said as he greeted Wednesday night’s audience during his opening monologue.

Colbert then expressed disappointment that he couldn’t head over to his desk to “talk about the unprecedented clustermunch it was,” saying, “We have an established format and as a responsible host, I have to choose the mature thing.”

The CBS funnyman then eyed the desk again, yearning to ditch the monologue in favor of sitting down to deliver his one-liners.

Suddenly, Sanders, a guest on Wednesday’s show, walked onto the stage.

“Stephen, you can do what you want and be responsible,” the Democratic presidential candidate said.

“But senator, these shows, you’re supposed to start with the host standing up talking to the camera,” Colbert replied.

“Stephen, that’s what the elites want you to think,” Sanders said to laughs. “You’ve got to follow your heart. Go your own way. The revolution is possible. You are the revolution!” Sanders continued, echoing some of his campaign’s message. “And this time the revolution will literally be televised."

Sanders then took it upon himself to introduce fellow “Late Show” guest Ben Stiller.

“Then, I’ll be sitting down with presidential candidate Bernie Sanders,” Colbert said.

“Wow! How did you get him? He’s electrifying!” Sanders, exhibiting faux shock, exclaimed.

Sanders delivered one more line before kicking off the show, saying, “Last night Bernie Sanders won the New Hampshire by 22 points — no joke!”

The tables were turned by the time Sanders sat down for an interview with Colbert, as the late-night comedian offered some guidance of his own to the White House hopeful.

“I am from South Carolina, so I wanted to educate you a little bit on my home state. If you’re going to get the vote down there, you have to eat boiled peanuts,” Colbert said, as he whipped out a pail filled with the snack.

“Delicious. Beautiful,” Sanders said as he cracked open a peanut and took a sip of beer.

“And this wins me South Carolina?” a seemingly skeptic Sanders asked Colbert.

“Yes, it does. If you like boiled peanuts, it’ll certainly give you a leg up in South Carolina,” the Palmetto State native replied.
