|“||Be a good little monkey!||”|
— Ted to George
Theodore "Ted" Shackleford is a deuteragonist, the second important character, who is a human and first befriends with George, also acts as his primary teacher, and mentor, and a deuteragonist in movies and episodes. Ted acts as George's monkey parent and also is an important fatherly figure to him.
He's known to be tall, intelligent kind, friendly, gentle, hard-worker, and very independent. He is also characterized by wearing a large yellow hat. He doesn't actually wear his hat at home, only when he goes outside.
He also owns a country house that has been in his family ever since his childhood memories, and lives in a spacious, high income apartment building in the City in Chicago.
Ted primarily drives a yellow Volkswagen convertible car as his main transportation to the Country, however, he typically walks when staying in the apartment. He also uses an open-top Hummer for off-road travels. He is an herpetologist.
Ted makes a couple of references to "going to work", however, we never discover what this pertains to.
In Curious George and the Invisible Sound episode, he has been asked to survey animals around the country house, and in The Fully Automatic Monkey Fun Hat, Dr. Wiseman has asked him to give a speech about the scientific method.
He is also the leader of a troop of the Sprouts, which George and Bill belong to. He paints and draws in the style of the H.A. Rey drawings.
He won an award for being the first to climb and map what became known as Yellow Hat Mountain and placed seventeenth in a marathon.
Ted is of the Scottish ancestry. His Uncle Tam, who lives in a castle in Scotland. Their family crest is a Dragon with the Yellow Tam.
No mention of his parents is made, other than an occasional reference to his mother in a couple episodes.
