Don't laugh, your life sucks too, you're reading this blog.
Schadenfreude
You tripping = Hilarious.
You tripping down the stairs and breaking your arm in three places = Best day ever.
Lots of different type of people like lots of different types of things. Instead of starting a crappy blog for each different type of person, and elaborating on each thing they like to no end, we decided to make one big crappy blog, about all kinds of people and the things they like. So suck it.
