Alanis Morissette's 'You Oughta Know': The Real Story Behind the Revenge Anthem

In 1995, an unknown Canadian singer named Alanis Morissette burst onto the scene with a blistering, fiery rock track called "You Oughta Know." They'd always said hell hath no fury like a woman scorned, and Morissette proved it to be very, very true.

The song begins pretty subdued, with Morissette calmly stating that she's not only happy for her ex, but that she "wishes nothing but the best for you both." Wait... both?

Instantly, her tone changes. She makes it clear that the mystery man she's singing about, to whom she later refers as "Mr. Duplicity," cheated on her with someone older - someone who wouldn't, as she puts it, "go down on you in a theater." To say she feels betrayed is an understatement. She sings to Mr. Duplicity, "You told me you'd hold me until you died - but you're still alive."

"You Oughta Know" was the lead single off Morissette's seminal album Jagged Little Pill, which remains her magnum opus 30 years later. While it was her third album released on a major label, it was her first released outside of Canada. But the smashing international success of Jagged Little Pill took everyone by surprise.

"Prior to the album's release, our thought was that Jagged would hopefully sell 250,000 units, which would give the label and everyone incentive to have Alanis make the next record," record exec John Alexander told Songwriter Universe Magazine. "But when (L.A. radio station) KROQ started playing ‘You Oughta Know,' it was a breakthrough that no one had anticipated."

Who Is Alanis Morissette Singing About In 'You Oughta Know'?

The success of "You Oughta Know" begged another question: Who is Morissette rage-singing about?

Common consensus has long had it that the song is about Dave Coulier, who played Joey on Full House. The two dated in the early '90s, when she was 18 and he was 33. While Morissette has never publicly confirmed the identity of Mr. Duplicity, Coulier has admitted that the song's lyrics hit a bit too close to home. Specifically, the line, "I hate to bug you in the middle of dinner."

"We had already broken up….She called and I said, ‘Hey, you know, I'm right in the middle of dinner. Can I just call you right back?'" Coulier told HuffPost Live (via Us Weekly) in 2013. "When I heard the line, it was like, uhhh-ohhh!"
