stealing cookies

[toast]

Okay, so there's this really annoying kid in my class you like stalks me around and is super obnoxious, so I've decided to try and take his facebook (where he basically just posts pictures of star-trek) login information for teh lulz

So, I just made a javascript that makes it so cat pictures fly around your screen.
now, SECRETLY it takes the cookie information and sends it to an email

I'm going to try basically turn my cookies into his cookies, and hopefully it'll log in as him
