Stephen Colbert and Conan O'Brien guest on each other's shows: 'Go ahead and host me!'

Who was hosting who here?

The hosts have become the guests.

Let’s see how that goes for them.

The Late Show’sStephen ColbertandConan’sConan O’Brieneach appeared as guests on each other’s late-night talk shows this week.

The duo still kept their audiences or lack thereof entertained in a comedic battle for hosting dominance.

“So you go right ahead, buddy.

Go ahead and host me!

All the weight’s on you now.

You fell into my trap.”

Colbert mocked O’Brien for not wearing a tie.

O’Brien mocked Colbert for looking like “a Senate page.”

O’Brien then became increasingly jealous of Colbert’s at-home setup.

“You are using state-of-the-art equipment,” O’Brien pointed out.

O’Brien, meanwhile, doesn’t even have an earpiece.

“We record my show on a flip phone,” he joked.

That’s how we’ve been doing it."

“I miss the laughter, I miss the joy that I bring others,” O’Brien said.

“What about your show?

Do you miss that?”

“I have no self-worth at all.

I only exist, really, in reflection to them chanting my name.

So, it’s been rough at times.”
