Harry Tang

From Chuck Wiki

Harry Tang is one of Chuck's coworkers at Buy More. Smug and overbearing, Harry is convinced that Big Mike is going to promote him to assistant manager, a position he obtains when Chuck fails to show up to his interview because of spy business. Harry is hated by the other Buy More employees, finds great pleasure in tormenting Morgan, and does his utmost to reign supreme over all employees after he is promoted. His one true love seems to be his flirty and unfaithful wife, Mrs. Harry Tang.

In a episode 8, "Chuck vs. The Truth," Tang moves to Hawaii with his wife, who we discover had been having an affair with Big Mike for six months; the affair was apparently the only reason Big Mike gave Harry the promotion since he felt guilty about "diddling the Lady Tang." Tang leaves with the belief that he is to be a new spy operative in Oahu, Hawaii - a smooth lie courtesy of Major Casey to explain themselves when Casey, Sarah, and Chuck were caught in the Home Theater Room talking to their bosses during Tang's investigation of what he believed will be an rendezvous between his wife and Morgan. Casey also further inflates Tang's ego and covers for Chuck when he tells Tang that Chuck was only a "small potato" to bring in Tang, the "big potato."
