Facebook Style Like & Dislike Stamps

Like Disklike Stamp
Since all your co-workers are on Facebook all the time, you might as well use office stamps they can relate to. You can show your approval/disapproval with written work with these Facebook styled stamps. And unlike the actual Facebook, this set of stamps comes with a “dislike” option. Why doesn’t Facebook have that yet?
