Dharma & Greg (1997)

Season 2: Episode 14

Role playing at a golf shop, the couple put on fake Southern accents and wind up endearing themselves to a genuine Southerner -- who turns out to be the federal judge before whom Greg must argue a cast the next day. After an evening's panic, he decides to tough it out and wins the case hands down (while mystifying Pete). But he discovers he has succeeded only too well: Judge Harper becomes the couple's best friend and constant companion, and Greg despairs at having to keep up the pretence forever -- especially when the judge comes to meet the entire extended family.
