Today I was watching Jeporady! & one of the catergories was "Royalty & Ballet". The question was something like "Before he became czar in 1890, he fell head over heels for ballerina Mathilde Kesshinsya." I was surprised to find out that someone knew that the answer was "who was Nicholas II?" Also in the "Worldwide Authors" they mentions Count Leo Tolstoy & also in "Royalty & Ballet" they mentioned H.M. Queen Margarethe of Denmark.
