Ozzy Osbourne and son, Jack, will be "circumnavigating the world" in their upcoming, 10-part History Channel series, Ozzy And Jack's World Detour, reports Rolling Stone. Only problem: Ozzy doesn't know what "circumnavigating" means. A trailer for the project finds Jack schooling his dad on world history (and vocabulary). Check it out below, and read more at RollingStone.com.

Ozzy and Jack,have been filming a new show since last fall for the History Channel, in which the Black Sabbath frontman travels to unique historical sites. According to Billboard, Ozzy And Jack's World Detour is set to kick off July 27th at 10 PM on the History channel and will feature the duo traveling the world together, exploring the history behind some of the planet's most storied sites, while checking out some lesser known locations along the way.

The Black Sabbath frontman told Billboard last year the 10-part hour-long series is "like a father and son spoof on history." He said, "We went to Stonehenge and met a guy who thinks he's the fucking reincarnation of King Arthur. And we went to Bletchley Park to see the machine (Alan Turing) used to break the (German) kind. We're going to Mount Rushmore, to the abandoned silos where America used to have their Minutemen missiles and all that. It's educational for me, actually -- history with an Osbourne slant."

Osbourne recently spoke with Rolling Stone about the show:

"After The Osbournes TV show, my son chose to go behind the camera and he's got his own company. He said, 'Would you be interested in doing this show?' And I went, 'Oh, great, fine.' I just got back from Cuba last week, which, incidentally, if you get any chance to go over there you should go, mate. It's fucking great."

"They got parts of a fucking U-2 plane lying around in this military thing in a park and you can just go and touch it. And I'm going, 'Fucking hell. If that was in England or America, they'd have a fucking screen that you couldn't touch this stuff.' Then somebody pointed out to me that under the Castro regime, it's everybody's property. It's not a government thing … but it's kind of weird."
