Dave Coulier, Full House Costars, Joke About His Ex Alanis Morissette’s Song “You Oughta Know”

His buddies oughta know! Dave Coulier just can't escape from his ex Alanis Morissette, and her smash 1995 classic "You Oughta Know," infamously inspired by him and their breakup. During an appearance on Watch What Happens Live Thursday night, the actor was grilled by Andy Cohen and his former Full House costars John Stamos and Bob Saget about the angry, raunchy jilted-love song — lyric by lyric.

"Was your next girlfriend after Alanis an older version of her?" host Cohen asked in the musician's voice, as the old pals laughed. (One line from the song reads of Coulier's imagined new girlfriend: "An older version of me? Is she perverted like me? Will she go down on you in a theater?") "Yes she was 87 years old," Coulier, 54, quipped back. "Was she perverted?" Cohen asked. "She was not," Saget, 57, responded for him.

Saget and Stamos, 50, stepped in for their friend during the question round, as Coulier sat blushing and laughing to himself. And at one point, Saget butted in to dish about his own Morissette memory. As it turns out, Saget himself was actually with Coulier when he hung up on the singer in the early 90s, which later inspired a lyric in the song. ("I hate to bug you in the middle of dinner," she wrote. "It was a slap in the face how quickly I was replaced.")

"I was at his house and he said, 'Alanis just hung up on me and said sorry for calling you during dinner,'" Saget recalled. "I was at his house when she said that to him."

Indeed, Coulier confirmed last September that hearing that specific line all those years ago was what made him realize the song was about him. "I called her and said, 'Look, what do you want me to say to the media when these folks call me?' And she said, 'You can say whatever you want,'" he told HuffPost Live at the time.

As for Stamos, he still wasn't convinced — until he bumped into the 39-year-old musician herself. "I ran into Alanis recently, and I said, 'That song wasn't really about him was it?'" the handsome actor told Cohen. "And she said, 'Yeah it was.'" 

But Stamos just couldn't believe such an angry song was about his comedian friend, who is known for his innocent enough stand-up. "She's so angry [in that song]," he added. "But she's singing about the guy that does Bullwinkle and Popeye [impersonations]."

Morissette has since moved on, and is now a mom to son Ever, 3, with husband Mario Treadway.
