At an archaeological dig, Kyle picks up a triangle that Cartman has discarded. Media attention from the find attracts Barbra Streisand, who needs the triangle to complete "The Diamond of Pantios." When she completes the diamond, she turns into a terrible monster that will require the combined efforts of Leonard Maltin, Sidney Poitier and The Cure's Robert Smith to defeat her.
This episode was funny but not always in a good way. The drama was still very childish throughout the whole thing. I liked it, however, because it was one of the earliest episode that showed celebrity appearances and poked fun at them.
