Okay... I'm reading about this for the first time and I disapprove strongly.
What's wrong with some people? That's the best course of action they choose for their free time? They'd be more useful as couch potatoes, at least then they wouldn't scare random strangers who probably have way better things to do.
And I seriously don't see how that's supposed to be funny. It's the kind of thing that's never funny, whether it happens to yourself or someone else. Just... no.
