Nah, you just get adverts you care even less about than those which have a chance of being some measurable fraction of relevant.
Most of the adverts I see seem to be based on what my contacts have "like"d, or otherwise interacted with, more than what I have done (though this could be in part due to me providing fb with a lot less info to work on than some of my contacts do) so providing fake information about yourself will make little difference there unless your contacts all do the same.
Empirically, it seems to work so far. My likes are quite eclectic, too, but that's by my design -- my homepage gets feeds related to Machete Kills and Oscar Wilde because I actually like both. Most of the ads are obviously wrong (hair conditioning products and club wear; I'm bald and hate clubs).
I honestly don't care about targeted advertising. Irrelevant advertising works fine for me.
