"They went to open the door, and I told the chauffeur to pull off."
Mark is not a popular man among his friends, he told Niall Boylan on 4fm, after running away from his wedding minutes before the ceremony.
Then,, the bride's aunt phones in to give him a piece of her mind.
The segment on Boylan's show was considering the news that Rory McIlroy and Caroline Wozniacki had split up shortly after the wedding invitations went out.
Looking to find out if listeners had any opinions on this - and if anyone had been in a similar late-cancellation situation - Boylan got a call from Mark.
Mark, it turns out, had a heart-to-heart with his father the night before his wedding, and started to think he'd made a mistake. But didn't decide until he arrived at the door of the church - and went home.
Leaving the bride at the altar. And yes, the father of the bride paid for the wedding.
"So you completely shattered this girl's dreams?" Niall asked.
"Yeah, for my own happiness - I realised this wasn't for me."
"I'm glad you did [leave her at the altar] because you're a scumbag," she said.
Then it kicks off, as Sarah reveals the bride is now happily married, and Mark changes his tune.
"He's welcome to her - the last few weeks I spent with her were hell on earth".
What do we reckon?
Mark argues that he changed his mind, and it would have been wrong to go through with the ceremony when he knew it wouldn't work out.
But perhaps he could have handled it better…
