Yoda

While on Skaro in the 27th century, Bernice Summerfield described the Seventh Doctor as "the worst Yoda ever". (AUDIO: The Lights of Skaro) The Eleventh Doctor once compared himself to "the little green one out of Star Wars" and proceeded to play with an imaginary lightsaber, but incorrectly named him Gandalf.
