Seriously imagine how sleazy and X Rated HBO would of made Barney Stinson or Ted or any of the other characters. All the amount of gross out extremely graphic uncomfortable sex scenes and situations it would of been like borderline porn! It would of made Girls or OZ look Rated G in comparison. The show could of been amazingly dark. It might of turned into a parody of HBO shows itself!
Watch Ted and Barney have a threesome together where they experiment with Bisexuality and are awkward afterwards. Watch Lily have an affair with another woman. Watch Barney snort coke off boobs and bums including Ted's bum! Seriously so much darkness potential.
