Dave Coulier recalls the first time he heard Alanis Morissette's 'You Oughta Know' and how he realized it was about him

• Dave Coulier opened up about the first time he heard ex-girlfriend Alanis Morissette's hit "You Oughta Know."
• He said on the "Jim Norton & Sam Roberts Show" one of his first thoughts was "I can't be this guy."

Dave Coulier recently revealed how he felt the first time he heard his ex Alanis Morissette's hit song "You Oughta Know" and subsequently realized that her career-defining album "Jagged Little Pill" was heavily inspired by their relationship.

On SiriusXM's "Jim Norton & Sam Roberts Show," the "Full House" star said he was in the car in Detroit with the radio on when "You Oughta Know" came on the airwaves.

He said his first thought was "this is a really cool hook" because he had "no idea" that the song was about their relationship. As it continued, it became clearer to him that events in his relationship with Morissette inspired it. "I'm listening to the lyrics going, 'Ohhhh...Oh No! Oh, I can't be this guy,'" he recalled.

Morissette and the comedian began dating in 1992 when she was 18 and he was 33. Their relationship lasted for two years, ending the year before "Jagged Little Pill" was released, Deadline reported.

Morissette has never publicly named Coulier as her inspiration for the song, but the timing of the romance and the release of the song fueled the widespread and generally accepted theory that he's the man that left Morissette with a mess when he ended things, as she sings about in "You Oughta Know." Coulier has confirmed as much himself.

Coulier said that after hearing the song, he immediately went to a record store and bought the full "Jagged Little Pill" LP. "I parked on a street and I listened to the whole record and there was a lot of familiar stuff in there that her and I had talked about," he said.

He mentioned that the lyrics "Your shake is like a fish," from the song "Right Through You," seem to be a reference to a dead fish handshake they did during their relationship.

"I started listening to it and I go, 'Oh, I think I may have really hurt this woman,'" he said, noting that this was his first thought while listening to the album.

When they reconnected years later, there were no hard feelings between the ex-lovers. "She couldn't have been sweeter," Coulier recalled of their reunion. He said she told him he could say "whatever" he wanted to about their past together.

The "Fuller House" actor said early in the interview that he "never saw" an "angry white girl" side of Morissette that the public focused on after the album's release.

The story he chose to share about his ex is rather touching. Coulier said that when his sister Sharon was dying of cancer, Morisette drove from Toronto to Detroit to visit with her in the hospital and serenade her.

"That's the kind of human being she is. So, I've never had anything bad to say about her. She's lovely," he added.
