Ozzy Osbourne and his son Jack finished up their latest season of "Ozzy & Jack's World Detour" and a newly surfaced clip has emerged from the series that is one for the books. The unaired clip features The Prince of Darkness meeting the parody tribute band, Mac Sabbath, and puts a McDonald's spin on legendary music.

Jack, along with his daughter Pearl, is taking Ozzy Osbourne to an undisclosed location and he looks frustrated as Jack talks about iconic moments in his dad's career. Once they arrive at the location, Osbourne once again is disgruntled when he sees a clown setup saying, "What the f*** is this?"

"Let the madness begin," Jack Osbourne says before the parody group drops the curtain and plays the riff of "Iron Man."

Ozzy Osbourne is enthralled by what he sees—"Ronald Osbourne" portraying Osbourne with a flaming frying pan. "Cows, we're going to grind/ Hope my stomach is well lined," the leader of the parody band growls. 

What once was annoyance had turned into admiration as Ronald Osbourne relives some of Ozzy Osbourne's most famous moments.

"It's fun. If you can't stand the laugh, don't f***** do it!" Osbourne laughed.
