Chuck Versus the Ex

Chuck runs into his ex-girlfriend Jill while on a Nerd Herd call. In an attempt to save face, he lies to the girl who broke his heart and tells her that he is more successful than he really is. 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 company efficiency expert Emmett to implement a mandatory CPR course taught by Captain Awesome.
