Over all five seasons, I'm not sure Natasha ever bothered to learn her nemesies' names on the 'Rocky and Bullwinkle Show'. At least she recognized Boris when she saw him. I didn't realize until recently that Boris & Natasha were the names of Tolstoy's lovers in War & Peace. If that book had featured moonmice, maybe it too could have been promoted to immortality on saturday mornings and cereal box covers. Then again, moonmice are not the answer to everything. Just most things. Hokey smokes!
