To be fair, Dave Coulier isn't the only suspected subject of Alanis Morissette's "You Oughta Know," and we may never know for sure because Morissette has refused to identify the guy. It might be Bob Saget, or even Matt LeBlanc. Maybe, just maybe, Alanis Morissette accidentally got hold of a time-warp viewfinder, gazed into the future, saw herself being abandoned by the fictional television character Andy Botwin, and wrote a song about how shitty a dude her future self once dated.
