Ringing Up Baby - S2.E1

A new path in life opens suddenly at the newlyweds' feet when Donna, the express checkout girl at their local supermarket, reveals that she has been dumped by her boyfriend just as she is about to bear his child. When Dharma brings her home for the night, Donna gets a bright idea: why doesn't she give the baby to Dharma and Greg? Greg is dead against the idea but.... you can guess the rest except maybe the fact that the baby turns out to be black.
