Chuck needs more fans. vote for that one.
Your options are...
How I Met Your Mother
Vote as many times as you want.
And if you don't give a shit for any of those shows, vote a couple of times for Supernatural. Because I want it to win, and I bring light and joy to this board like text based Jesus.
His cover is boring though.
I have never seen even a second of Chuck, which I know is kinda lame.
The Bones and HIMYM covers are the only ones with good pictures. Both leads look goofy in the Castle one (and Stana Katic is usually really hot so it's weird), Smallville has a bunhc of people who haven't been on the show for years, Chuck's is boring, and the Supernatural one is boring and looks to be at least a few seasons old.
It's a bit like having sex with a jellyfish: once might an interesting experiment, twice would be perversion!
You never know what worse luck your bad luck has saved you from.
Either Bones or Supernatural.
