Facebook, Stop Freaking Me Out

I don't like that Facebook seems to know me intimately. I just read two of their sidebar advertisements:

1) 2 Miniature Poodles for sale! Please give them loving homes!

2) Pittsburgh T-shirts for sale! Show your pride!

How do they know that Pittsburgh's secretly been winning me over OR that I have an unhealthy obsession with puppies, specifically poodles!? I don't understand! The internets has invaded my brain!

Also, I should note: Hooray Penguins!!! 2 major wins in one year, how do you do it, Pittsburgh?
