49. Dave Coulier and Alanis Morissette
Couple Nickname: None
Dated Between: Unknown
Dave Coulier may have been the inspiration for one of Alanis Morissette's best songs of her career, "You Oughta Know," but that doesn't make their actual relationship any less lame. If the things that Alanis described in her song were true —accusations of infidelity, and overall jerk behavior from Coulier, to be specific—then their time together seems like it was pretty toxic.
Sure, the lives of a lot of angry young women would probably be a lot different without the existence of the song, but with biting lyrics like, "Well, I'm here to remind you/ Of the mess you left when you went away," it seems like Morissette's life would have been better without Coulier. Full House was a lie.
