This is not a joke, but it's a part of an internet culture development that needs to be put to death. I would rate this as one of the most serious moral crimes a person can commit, right up there with genocide or raping children. People that has allowed themselves to be sucked into the whole distanced internet culture to the point where they no longer laugh at all, the snort a little and say "lol", which stands for laughing out loud. By this point you are no longer even a human.
