Dear John is a sitcom that aired on NBC. The series is based on the UK program of the same name.
Dear John starred Judd Hirsch as easy going high school teacher John Lacey who is dumped by his wife, Wendy, via a Dear John letter. Wendy ends up with everything in the divorce settlement, including custody of the couple's son, forcing John to move into an apartment in Queens.
John soon joins the One-2-One Club, a self help group for divorced, widowed or lonely people. The group is led by Louise, a sex obsessed British woman. Other members of the group include Kate McCarron (Isabella Hofmann), a sweet divorcée, Kirk Morris, a cocky ladies' man seemingly stuck in the '70's, Ralph Drang (Harry Groener), a shy and neurotic tollbooth collector, and Margie Philbert, a feisty senior citizen.
