It’s about midnight on a Tuesday in 2011. You’re flipping through channels. You stop at CBS because there’s a Scottish guy with a mohawk yelling at a plastic skeleton wearing an identical mohawk. The skeleton has a metallic blue arm and a voice that sounds like George Takei having a breakdown at a luau. This shouldn't work. By every rule of television production, it’s a disaster. Yet, Craig Ferguson and Geoff Peterson somehow became the most authentic duo in the history of late-night TV.
Honestly, we don’t talk enough about how weird it was. Most talk shows are polished to a mirror finish. They’ve got house bands, sleek desks, and sidekicks who laugh at every mediocre joke. Craig Ferguson didn't want any of that. He wanted a "Robot Skeleton Army," and he ended up with a masterpiece of deconstructionism.
The Birth of a Legend (and a Twitter Challenge)
The origin story isn’t some corporate strategy meeting. It started with Craig complaining. He’d joke on air about how the "big shots" at the network wouldn't give him a sidekick or a band. So, he decided to build his own.
In early 2010, the late Grant Imahara from MythBusters saw Craig’s rants and tweeted a challenge: if Craig could get him 100,000 Twitter followers, Grant would build him a robot sidekick for free. It took less than 24 hours. The internet, even back then, knew a good bit when it saw one.
Geoff Peterson made his first appearance on April 5, 2010. At first, he was just a prop. He had seven pre-recorded phrases. Craig would hit a button on his desk, and Geoff would say, "I've got a place in the East Village" or "That's cold, Craig." It was funny for a week. Then it got repetitive.

Everything changed when Josh Robert Thompson stepped into the booth.
Why Josh Robert Thompson Was the Secret Sauce
If you’ve seen the clips where Craig is literally crying from laughter, that’s Josh’s fault. He wasn’t just a voice actor; he was a world-class improviser.
By June 2011, Josh started voicing Geoff live. This was the turning point. Suddenly, Geoff wasn't a machine; he was a sentient, sarcastic, "gay robot skeleton" who lived to derail Craig’s monologues. They didn't have scripts. They didn't have rehearsals. They just had two microphones and a shared sense of the absurd.
The "In Your Pants" Phenomenon
One of the most famous bits—the "Custom Butt Sponge" or the "Daffy Dook" moments—usually started because Josh would say something so wildly unexpected that the show would just stop. You've probably seen the video where they're talking about a "carefully curated" list, and it devolves into a ten-minute riff that has nothing to do with the guest or the news.

- Improvisation: 100% of the banter was unscripted.
- Physicality: Grant Imahara’s engineering allowed Geoff to move his head and arm, giving Josh enough "body language" to land a joke.
- Chemistry: Craig treats Geoff like a real person, which is the only reason the bit works. If Craig winked at the camera, the magic would die.
Deconstructing the Late-Night Format
Most hosts are terrified of silence. They’re terrified of a joke failing. Craig Ferguson and Geoff Peterson leaned into the failure.
They’d make fun of the cheap set. They’d make fun of the "Big Cash Prize" ($50 in quarters, later lowered to $7.50 in nickels to "save the network money"). They mocked the very idea of an interview. When a guest sat down, they weren't just talking to Craig; they were entering a bizarre three-way conversation where a skeleton might hit on them or ask if they’ve ever been to an Ennio Morricone concert.
Think about the "Awkward Pause." No other show would spend thirty seconds of prime-time television just staring at the camera in silence. It felt like you were in on a private joke. That’s why the show developed a cult following that persists long after its 2014 finale.
The Legacy of the Robot Skeleton
Is it weird to say a plastic skeleton changed TV? Maybe. But look at late night now. It’s mostly viral games and "Carpool Karaoke." It’s very safe.

Craig and Geoff were the opposite of safe. They were punk rock. They proved that you don't need a $20 million budget or a 15-piece horn section to make something memorable. You just need a guy who doesn't care about the rules and a robot who’s "got a place in the East Village."
The chemistry between Craig Ferguson and Geoff Peterson wasn't just about the jokes. It was about two guys—one human, one animatronic—reminding us that the best parts of life are the ones we didn't plan for.
How to Relive the Chaos
If you're looking to dive back into the rabbit hole, don't just watch the highlight reels. Find the full episodes from the 2012-2013 era. That’s when the "Secretariat" the horse (also Josh Robert Thompson) and the various puppets were in full swing.
Next Steps for the Fan:
- Search for the "Chard" clips: It’s a masterclass in how a single word can break a professional broadcaster.
- Follow Josh Robert Thompson: He’s still active and frequently talks about the "Geoff" days on his own podcast and social media.
- Look up Grant Imahara's build logs: For the tech nerds, seeing how a MythBuster actually wired a late-night sidekick is fascinating stuff.
The show might be over, but the "Robot Skeleton Army" is still out there. And somewhere in a storage locker at CBS, Geoff Peterson is probably still waiting for his next cue.
