Synopsis by Hal Erickson
Christina Hart guest stars as Karen, the niece of Stanley and Helen Roper (Norman Fell, Audra Lindley). Still convinced that his tenant Jack (John Ritter) is gay, Mr. Roper feels it is safe enough to give Jack 50 dollars and ask him to take Karen out on the town. Besides, if Jack turns out not to be gay, Roper will have an excuse to kick him out of his apartment. The fun really begins when Karen is revealed to have a unusually voracious sexual appetite. "Roper's Niece" was originally intended as the final episode of Three's Company's short first season, but ended up being shown as the third entry.
