THINGS got very heated on Studio 10 this morning as Kerri-Anne Kennerley blasted one of The Chaser comedians for the group’s overnight prank on Alan Jones.

In a video released online early this morning, Chaser member Charles Firth is shown driving around Sydney and projecting an image on iconic buildings including Parliament House and the Opera House. The message said “ADVERTISE HERE: Call Alan,” and then listed Alan Jones’ personal mobile number.

The stunt was in protest of the shock jock’s support of the plan to promote a $13 million horse race on the sails of Sydney Opera House later tonight.

Firth appeared on Studio 10 this morning to discuss the prank and co-host Kerri-Anne Kennerley made it clear from the outset she didn’t think it was funny.

“Why did you put his number up there? Why?” she asked Firth.

“So that everyone would call him and then he’d back down and apologise,” Firth said.

“I think it’s very clever what you did for your show, but the number?” Kennerley said. “I just think that was going too far.”

Firth said The Chaser team had debated whether or not to go ahead with the stunt and said some team members thought “it was a bit of a horrible thing to do to a person”.

He then added, “But he’s (Alan Jones) been horrible to so many women.”

Kennerley took exception to that comment and said, “What a heck of absolute rubbish!

“Yes he’s got a temper and he can sound very hard, but there are a lot of times where he’s done amazingly fabulous work and I don’t think it’s got anything to do with being a woman,” she said in defence of the 2GB radio host.

Kennerley then pulled a stunt of her own and demanded to know Firth’s mobile number which she then wrote down on a piece of paper and held up to the camera.

“Call Charles, there you go,” she said to viewers at home.

Continuing her attack on Firth, Kennerley slammed the comedian for pulling the stunt without reaching out to Jones.

“So you never knew him, you’ve never spoken to him, you didn’t ask him for a comment,” she said.

“Did you ask Louise Herron (Opera House chief executive) why she did the three-year deal with Samsung to project photographs on the Opera House? Did you ask her that? Have you spoken to Louise Herron, yes or no?”

As Kennerley’s barrage continued, co-host Sarah Harris came to Firth’s aid and suggested they should let their guest speak.

“The problem with Alan Jones is that he thinks the only people who should be able to do things in this city are the well-connected and the rich,” he said.

“So let’s get down to basics,” Kennerley replied. “You hate people with wealth … And you work for the ABC? And who funds the ABC?”

“Everyone,” a confused Firth replied.

“Yes, exactly,” Kennerley said before adding in a sarcastic tone, “The ABC is so balanced, that’s what I love about it.”

“I don’t actually work for the ABC,” Firth told her. “I work for a very small non-profit called Triple M,” he joked.

At the end of the fiery segment during which Firth’s phone didn’t stop ringing after having his number shown on air, Kennerley attempted to bury the hatchet by saying, “We can always agree to disagree.”
