When a British couple embarked on a sightseeing trip on Hollywood Boulevard, they hoped it would be a once-in-a lifetime opportunity to see the homes of the rich and famous, and perhaps catch a glimpse of an actor passing by.
Mr Hobden, 55, and his partner said they were left "babbling" in shock after being propelled from their ordinary tour-bus into the 89h Academy Awards, taking photographs of Nicole Kidman, Jennifer Aniston and Ryan Gosling and finding themselves in conversation with Denzel Washington.
The unsuspecting pair, who were on a dream holiday in the States, had booked a ticket for a sightseeing tour and boarded a bus alongside eight other holidaymakers.
But after zigzagging around the city sights, their coach drove down Hollywood Boulevard and pulled up outside the Academy Awards for a prank insigated by television host Jimmy Kimmel.
Viewers of the awards will recall seeing a bus-load of bewildered tourists being introduced to the ceremony wearing shorts, t-shirts and hooded sweaters among the glamorous gowns of other guests.
Among them were Mr Hobden, a carpenter from Bristol, and his partner of 12 years, office manager Ms Wozencroft.
Mr Hobden said: "They lifted up the fence and ushered us inside, past two big security guards and through a metal detector.
"They told us, 'This is a special tour,' and said we would be going to an exhibition to see all the gowns, and we might get to touch an Oscar. "We had no clue what we were in for whatsoever."
It was only when the doors opened to what they thought was the exhibition and they were dazzled by hundreds of camera flashes that they realised they had been set up.
The 'tour' was part of a stunt organised by American TV host Jimmy Kimmel, who broadcast the entire thing live on his YouTube channel. But the couple - who had no idea about that at the time - made sure they documented it all for themselves just in case their friends and family refused to believe them.
Mr Hobden said: "When the doors opened it was a surreal moment where all these people were clapping us. I just thought, 'Oh Jesus, we're at the Oscars.'
"I was just babbling, I couldn't speak properly. Shelly was shaking. We were in total shock. It was unbelievable. We were just awe struck."
The couple took photos with Nicole Kidman, Jennifer Aniston and Ryan Gosling, and they spotted other celebs like Halle Berry and Meryl Streep.
Actors Casey Affleck, Matt Damon and Samuel L Jackson were among the others they rubbed shoulders during the seven minutes they were given to mingle. "At one point, I turned round and was thinking, 'I recognise that guy.', " Mr Hobden said.
"He said, 'Hi, how you doing Pete?' I said, 'How do you know my name?' and he said, 'Because you've got a name badge on.'
"I said, 'I don't know your name because you haven't got a name badge.' Then he left and I walked past him and realised it was Denzel Washington.
"We were just awe-struck. All our friends and family are so jealous. "It was an amazing experience. We never thought we would go to the Oscars."
Ms Wozencroft, 50, added: "It was so surreal. Absolutely surreal. It is something I will never ever forget - we were treated like celebs in Hollywood. "It was just incredible. It was the best experience of my life."
Eight lucky tourists made it into the Oscars as part of the stunt, including a father and daughter from Ireland and two couples from America.
