I always believed they dropped the ball big time with Eugene. I would've had him do his retard thing and earn the trust of the world champ like he did.
Then, let there be some 4 way and Eugene in it to protect his friend the champ.
All of a sudden, Eugene turns heel, clobbers the champ and wins the title revealing he being retarded was just an act.
That would've been a great turn considering how over he was and how people believed he was retarded.
