Get the brohm and haasmug. 1.) A WWE wrestler on the RAW brand roster, who teamed with Rico, Shelton Benjamin and Former WWE Champion Kurt Angle. Charlie Haas is one of the most gifted wrestlers, to never get a single title push. His closest push was taken away by WWE officals as punishment for accidently injuring Lillian Garcia on an episode of RAW. Now Charlie Haas teams with Visera as a heel jobber team. Charlie is married to "Ms. Jackie" and is expecting their first child soon.
