That was probably the most failure attempt of a joke I have ever heard…
That being said boo hoo the kid was a retard who did some stupid shit. It sucks he killed 4 of his best friends but i dont think every 18 year old is stupid enough to go on a 1.5 mile long or whatever run way at night and not think that something might go wrong. The guy was a idiot and he died. It is sad but shit like this happens all the time and the only reason this is big news is because of his age.
He is at fault not his parents because anyone with half a brain has common fucking sense not to do retarded shit like that.
