'Mad Men': Lane Pryce Resigns (Season Five, Episode 12)
When Mad Men returned after a 17-month absence this past March, the show appeared to be suffering from a case of uncharacteristic jollies. Namely, Don Draper, womanizer extraordinaire, was happily married and displaying zero signs of infidelity. Yet the fifth season turned out to be especially dark, with the story line of Sterling Cooper Draper Pryce's financial officer coming to a bleak end in the penultimate episode. After learning that Lane had embezzled funds from the company to pay back taxes, Don was forced to demand the British expatriate's resignation. Personally and professionally humiliated, Lane hangs himself on the door to his office (following a bungled self-asphyxiation attempt in his brand-new Jaguar), leaving his bereaved colleagues to discover his dead body.
