Here's a list from Gizmodo.com of the eight creepiest things you can do on Facebook. Some these might be fun if your friends know you really well. If you do any of these to the girl you think is cute at the Taco Bell, You probably are creepy.

1.  Posting a photo of your face on someone else's wall with zero explanation.

2.  Tagging yourself in someone else's engagement photo.

3.  Commenting on someone's photo from 10 years ago as if it's current.  Like, if they're eating a donut, write, "Mmm!  Looks good!"

4.  Commenting on someone's life events you had no part in.

5.  Requesting someone's relationship status ... and their address.

6.  Friending someone's Grandmother.

7.  Poking someone's grandmother.

8.  Sincerely interacting and engaging with brands.  How screwed up will your friends think you are when they see you respond, "LOL" to a super lame joke that McDonald's or Verizon posted.
