Who Set Me Up?

Okay, I've had some freaky things happen in my life, and another one just burst out of the computer a minute ago. You see, I've never set up a TWITTER account because it seems, well, kind of annoying to have updates for every little thing someone does throughout their life.
Well, I've gotten enough followers of my non-existent Twitter account that I decided to bite the beak and give it a try. I mean, you don't really know unless you try it, right?
But guess what? When I typed my information, the Blue Twitter Bird told me that my email address was already taken.
Say what?
Well, I have been known to put library books in the fridge and just yesterday I lost my celery in the cupboard and was SO GLAD when Michael found it that I was willing to concede there was a remote possibility I'd set up an account without paying attention.
So I tried to log in, but since I had no memory of creating the account, I didn't know the password. So I clicked on "Forgot Password," and was sent a re-set password link... but LOOK HOW MY NAME IS SPELLED! "Hi, ShirleyBahlman"
Now I KNOW I didn't set that up, because I happen to know that, no matter how unnecessary they both seem, my last name is spelled with 2 "N's" at the end!
So what I want to know is... who set me up?!
