The sense of humor that is found on the internet is never more wicked than in the comment section. 

The kind of thing that some may hold back on posting to their profile for all to see always seems to find its way under a post that somebody else makes, with a little extra spice added just for fun. Quite often, the wordsmiths of the internet find that their greatest inspiration is other people, or at least the kind of things that they see fit to post on social media. The world is a ridiculous place made even more ridiculous by being online all the time, and the average serial commenter is constantly reacting to that.
