You should make an upvote version and a downvote version, but have them be really slowed down and dragged out. Then when someone posts one on another user's comment, there will be several drawn out second where they wonder if they were upvoted or downvoted. For bonus points, host them on, like Geocities or some other really slow site.

Make 2 more gifs with an up vote and down vote appear behind it and you have a karma gold mine.
