Do you remember toomanykooks? He used to post ere once he did

Anyways I was browsing facebook and looked in the corner to find his drunken face staring at me, looked away is dismay rubbed my eyes and glanced back and he was still there... staring at me.

After I regathered my thoughts it turns out facebook can recognise faces you haven't tagged now and like a paranoid lover started asking 'WHO IS THIS?!@?!?!?!??!?!?!'

I will never be the same :(

So when did this feature come in?
