Frank Oz (born May 25, 1944 in Hereford, Herefordshire, England, UK) is a director and actor best known for his work with Jim Henson's The Muppets franchise and as the voice and puppeteer of the character Yoda who is seen in the Star Wars film franchise (which was covered by RiffTrax).
In summer of 2014, RiffTrax did a live riff of 1998's Godzilla. During the riff, Bill remarks that the main character (played by Matthew Broderick) isn't heeding Yoda's advice. Kevin Murphy then quips in a Yoda voice-over imitation: "Why bother do I?"
