There are even books about Wojtek, a bear cub adopted by Polish soldiers, who drank beer, ate cigarettes, carried ammunition and died in a zoo in Scotland.
In the late 1970s, Wojtek Fibak reached the Top 10 on the men's ATP Tour while much further back, Jadwiga Jedrejowsa reached three grand slam finals in the 1930s which -- even if she didn't win one -- is still the Polish record for the Radwanskas to beat.
