The former Full House funny man, Dave Coulier, and the Jagged Little Pill performer, Alanis Morissette, dated in the early 90's. Morissette's 1995 Grammy winning hit, 'You Oughta Know' is rumored to be about Coulier. Although Coulier has admitted in interviews that the lyrics hit close to home, Morissette has never admitted who the song is about.
