Can I put in a late vote for John Mayer? His claim to fame, as far as I can tell, is having written the most boring song of, like, 2001, then doing absolutely nothing else of note beyond briefly dating the other world's most boring celebrity. Here he is looking vapid.

most boring couple ever.

boring.

Look at his vacant eyes. BORING.

Mischa Barton is clearly the most boring celebrity. Besides dressing atrociously, what has she been doing lately?

I know you said “most boring,” but it seems like its trending to “most annoying.”

Kristen Stewart (of Twilight). I'm surprised no one has said this yet. Oh well.

Miss California (I don't even know her real name)

Zooey Deschanel. Just watch anything she's ever been in, you'll agree.

This guy.

The Banker

One of them… I forget which.

Chris O'Donnell. I call him Chris O'Dullard.
Just look at him. He's as exciting as paste.

Man, it's Ryan Seacrest's JOB to be boring. I can't be the only person who's noticed that!
