Most rage inducing thing you have seen on the internet:

So, I was on TF2 earlier, and this 5 year old girl joined the server, then these three guys started herassing her, then tried to make her tell her mother she "Loved osama bin ladin," And acted like ignorant assholes. I swear, If I could, I would kick them off the planet...
So, tell me, what the most rage inducing things you've ever faced.
