Joe Rogan has a hidden feature in his podcast studio that can't be seen on-screen

If you're a fan of Joe Rogan's podcast, which, I mean, is very likely, considering how many listeners he has, this one is for you.

Over the years, the comedian has spoken to some of the biggest and most controversial names in the world, from Quentin Tarantino and Alex Jones to Miley Cyrus and Edward Snowden.

He's had them all in with him.

But while you might be an avid listener, and maybe you've never missed an episode, there's a hidden feature of Rogan's studio that you may never have seen before.

The main reason for this is because it's actually out of shot, and with the camera only ever really focusing on Rogan and his guest, it's unlikely that it would ever pan round far enough.

However, in a video posted to YouTube recently, the host gave a mini tour of his Austin studio, and showed off his wall of mug shots.

Ok, I'll admit, it's not like he's got a pile of dead bodies in the back, but it's a pretty interesting piece of office decor, right?

In the video, Rogan pans round and unveils a wall filled with the mug shots of Pablo Escobar, David Bowie, Rosa Parks, Jim Morrison, Jimmy Hendrix and Mick Jagger.

Rogan hit the headlines recently after he called out a couple of the biggest names in Hollywood for using steroids.

The ever controversial podcast host said there was 'not a chance in hell' The Rock is clean, after the Liver King admitted to using steroids - following years of denial.

But he wasn't done there.

Speaking on The Joe Rogan Experience podcast, he asked guest Derek: "Do you think Jason Momoa's on the sauce?"

The founder of the More Plates, More Dates fitness website replied: "I think my conclusion at the time, that was a really iffy one, because the guy is just a built f***ing dude to begin with, with like a big frame.

"But it would be safer to assume than not that he probably did a little something for his peak superhero."

Moving on to Thor actor Chris Hemsworth, Derek claimed he 'sauced it up, 100 percent', and Rogan concurred.

"Yeah, I think so too," he said. "Not that there's anything wrong with that."

Derek added: "Hemsworth packed on like 20 pounds or 30 pounds in a matter of like six months or something absurd.

"Anyway, if you look at him before Thor 1 it was like, a night and day difference. He looked like a surfer dude."
