'Mr Angry' as a humorous charactor has been done before - and like most humo[u]r, subtlety and timing is essential to make it work. An endless rant or tirade by itself is not very funny.

The most humoro[u]s aspect of this guy's site is the fact that people actually stop to read any of it.

As for the charactor being funny?
