It's All Relative (2003)
It's All Relative is a 2003 comedy series created by Chuck Ranberg and Anne Flett-Giordano. It stars Reid Scott, Maggie Lawson and Lenny Clarke.
Bobby's a bartender and the only son of gregarious, salt-of-the-earth Irish Catholic parents from Boston. His fiancée, Liz, is a toney Harvard student and she's Protestant (no, that's not the problem). Liz has two dads, not one, and they're a worldly pair of well-heeled gay men.
