To the guy who mentioned 3 guys 1 hammer, I suggest you do not go looking for it because it will lead to bad things. I stumbled upon a youtube reaction video to 3g1h, and the kid had the sound turned all the way up or something because just the sounds of the video alone were making my stomach churn and I didn't even watch it! Then, being the curious person that I am, I wanted to know more about it. Being completely stupid, I went onto Encyclopedia Dramatica and looked it up. Wish I never had. Consider that a warning.
I've heard goatse is really bad, but don't really know what it is nor to I really want to.
