Dave Coulier says he didn’t recognize the portrayal of him in his ex-girlfriend Alanis Morissette‘s song “You Oughta Know” the first time he heard it.

The Full House star appeared on an episode of SiriusXM’s Faction Talk released on Tuesday and admitted that it took listening to the entirety of the singer’s 1995 album Jagged Little Pill for him to realize just how deeply he had hurt her. Coulier explained that he heard the song that is rumored to be about him for the first time on the radio that year as he was driving around Detroit. He said he was really enjoying it and then suddenly recognized the singer’s voice and thought, “Ooh, oh no! Oh, I can’t be this guy!” After hearing the song, he went straight to a record store where he purchased the entire album and then parked his car on a street and listened to it from start to finish. “There was a lot of familiar stuff in there that her and I had talked about,” Coulier continued. “Like [in ‘Right Through You’] ‘your shake is like a fish.’ I’d go, ‘Hey, dead fish me,’ and we’d do this dead fish handshake. And so I started listening to it and I thought, ‘Ooh, I think I may have really hurt this woman.’ And that was my first thought.”

Morissette and Coulier first started dating in 1992 when she was just 18 and the actor was 33. They broke up after two years together and the following year she released what would become her first Grammy-winning album. But because Morissette has never confirmed or denied the speculation around who she wrote those songs about, she said that a number of men have stepped forward to claim the title, assuming they’re the album’s protagonist. In 2019, she told Andy Cohen on Watch What Happens Live that while she would not reveal the identity of her past bad boyfriend, “I am intrigued at the thought—or at the fact—that more than one person has taken credit for it. I’m thinking, I don’t know if you want to take credit for being the person I wrote ‘You Oughta Know’ about. There’s been about six people that have taken credit for it.” She added, “I just think, if you’re going to take credit for a song where I’m singing about someone being a douche or an asshole, you might not want to say, ‘Hey! That’s me!’”
