Chuck Versus the Ex (S02E06)

While on a Nerd Herd call, Chuck runs into his ex-girlfriend Jill -- the girl who broke his heart. In an attempt to save face, he lies and tells her that he is more successful than he really is. But when Chuck flashes on Jill's boss -- a research scientist who may have developed a deadly bio weapon -- he, Sarah and Casey must find out if Jill is involved. Meanwhile at the Buy More, Big Mike nearly chokes to death, which leads the company efficiency expert, Emmett, to implement a mandatory CPR course, taught by Captain Awesome. (Warner Bros. UK)
