HOLLYWOOD, Feb. 18 (UPI) -- The DNA of "The Simpsons" reaches as far back as the classic films of Laurel and Hardy, the creators said on the eve of the show's 500th episode.
Dan Castellaneta, who does the voice of Homer Simpson, told The Hollywood Reporter his trademark catchphrase "D'oh!" was inspired by one Jimmy Finlayson, a longtime supporting character in the Laurel and Hardy shorts who would give a drawn out "Doooooooh" whenever he was hit in the head or had generally had his fill of Stan and Ollie's antics.
