OK, this is one of the funniest (and most chilling) things I've come across in years. It is a joke folks!! Don't take it seriously but it is simply wonderful!

The thing about it is that it could happen...I especially enjoyed the comments about socio-pathology that occur in corporate America (near the end). Pgardn will enjoy this I think, as well as fans of the mythology:
