Peacemaker Season 2's Funniest Post-Credit Scene Was Completely Improvised

You know that awkward, end-credit bit in Peacemaker season 2 where Economos tries to tell a joke and kind of face-plants in real time? That was not on the page. Steve Agee says he made the whole thing up on the spot, and honestly, it tracks.

The punchline is there was no punchline

Talking to FandomWire, Steve Agee (John Economos) said the season 2 finale tag — the one where he starts telling A.R.G.U.S. agents a joke about a Massachusetts truck driver — was entirely off the cuff. There isn’t a clean setup or a satisfying payoff because he was winging it. The comedy is the struggle.

That is all me literally struggling, and then just kind of giving up and going.

And it works because you can feel him trying to land the thing, missing, and spiraling. By the end, one of the agents breaks and laughs uncontrollably — that crack-up was something James Gunn added.

How Gunn lets the chaos in (just a little)

Agee also gave a rare peek at how improvisation happens on James Gunn’s sets. Gunn is famously precise with his scripts, but he’ll call an audible and tell actors to riff when he thinks it will juice the scene. Most of what you see on Peacemaker is written, but when Gunn says, 'just say something here,' they go for it.

What was scripted vs improvised in episode 8

• The finale scene starts with Economos trying to distract a room full of people. The baseball chatter — including a throwaway line like 'Did you catch that prawns game?' — was written by Gunn. Agee even admits he didn’t know who the Prawns were; that was all James.
• The messy Massachusetts truck driver joke in the post-credit scene? That was Agee inventing it in the moment, no traditional setup or punchline.
• Agee says he’s not a stand-up, so the tension and awkward pauses are the point. It isn’t a crafted joke; it’s the uncomfortable build that makes it funny.
• Gunn topped it off by having an agent lose it laughing, which pushes the awkwardness into a proper button.

Why the bit lands

It’s the blend: Gunn’s tight writing gives the scene a spine, and the improv gives it that chaotic, real-time flop-sweat energy. You’re watching a character fail to be funny, and somehow that ends up being the funniest part of the episode.
