He has more than 20 years of broadcasting experience, but Late Late Show host Pat Kenny proved no match for rock idol Pete Doherty last night.
The RTE star was put firmly in his place by the Babyshambles frontman, when Pete refused to be questioned any further about his much-publicised drug habit or love life, instead turning the tables on Kenny.
"I don't know if you could name a song that I've written?" he asked the broadcaster, to which the clearly unprepared host could only reply: "No, possibly not."
"I don't understand why this has to be the be all and end all of how you look at someone and judge someone," Pete said of his drug problem.
"The last 12 questions you've asked me have been about drugs," he added, before pulling his hat over his eyes and refusing to engage any further, leaving Pat at a loss for words.
In a bid to recover from the embarrassing blunder, Kenny went on to ask the Babyshambles singer to play a song for the audience, before quickly putting an end to the disastrous interview.
In typical rock and roll fashion, Doherty had rolled into town two and a half hours late for an appearance at Trinity College earlier that evening.
Carrying a cigarette in one hand and a bottle of beer in the other, the singer had no qualms about lighting up indoors and breaking the smoking ban, as he proceeded to smoke a number of cigarettes while giving his address in front of more than 200 people.
Breaking his silence about his son Astile for the first time, Pete revealed he now enjoys a much closer relationship with the child.
"It's quite a difficult subject," he said. "We're ok. That's why I got his name on my neck, because I saw so little of him. It's my way of saying I love him."
And while he was reluctant to speak about his battle with addiction, the star did confirm that he is now leading a "mostly clean" life. According to Doherty: "I'm coping mostly, I won't lie to you, it is a struggle. I don't know what to say, but I'm mostly clean."
But his controversial lifestyle proved no deterrent for the crowd of eager fans who turned up at Trinity College in the hope of catching a glimpse of their idol. From mid-afternoon a queue began to form outside the Graduates' Memorial Building, with admittance to the event strictly by presentation of a Trinity student card.
The singer (29) had been invited to the college by the Philosophical Society and spent more than 40 minutes with students as he answered questions from Hot Press writer Stuart Clarke, as well as playing songs, including Substitute, on his guitar.
The singer's later appearance proved not to be the first problem encountered by Pat Kenny during the evening. Earlier, the controversial Irish language poet Cathal O Searcaigh pulled out of a planned appearance on the show.
The poet cancelled his involvement with the show when he was informed that RTE would abide by legal advice not to screen the interview live, and instead pre-record it. Lawyers wanted to vet his remarks before they were broadcast.
The poet (52) objected to the proposal and pulled out. He had initially contacted the show and offered to be interviewed.
His offer was accepted as the show had previously been seeking to interview him following the controversy last year following a television documentary about his sexual relationships with young men in Kathmandu, Nepal.
The gay poet said he was financially supporting a number of boys and young men in the poverty stricken country.
He confirmed he had sex with a number of youths in his hotel room, but that none of them were coerced and that they were over the legal age to have sex.
