A resposta certa era: Teddy Bear.
De acordo com o Brewer's Dictionary of Phrase & Fable (Weidenfeld & Nicolson, 2005): «A child's toy bear, named after Theodore (Teddy) Roosevelt (1858-1919), who was fond of bear-hunting. Roosevelt was shown sparing the life of a bear-cub in a cartoon drawn by C. K. Berryman in 1902 as a spoof on the president's role as an ardent conservasionist. In 1906 the New York Times published a humurous poem about the adventures of two bears named Teddy B and Teddy G in his honour. These names were then given to two bears newly presented to the Bronx Zoo, and manufacturers seized on the event to put toy bears called Teddy Bears on the market» (pg. 1362).
