Let's go some CSS up in heeeaaaa!!
If you're going to use a helper, there's actually some given to you by the font-awesome-rails gem that you're using https://github.com/bokmann/font-awesome-rails#helpers

```html
<%= link_to fa_icon("thumbs-o-up"), episode_vote_path(episode, 1), method: :put %></i>
```

You should also remove that extra closing `</i>` tag.

```html
<%= link_to fa_icon("thumbs-o-up"), episode_vote_path(episode, 1), method: :put %>
```

If you don't want to use the font-awesome-rails helper, you should at least use the 1.9 hash syntax
