I realize that this has absolutely nothing to do with the economics of virtual worlds, but I can’t help but love this video. Yes, it’s been around a while, but every few months I see something about and I watch it again and it makes me laugh.
My favorite part: When Leeroy defensively proclaims "It's not my fault!" right after he causes everything to fall into the crapper.
