Joseph Francis Alaskey III (April 17, 1952 – February 3, 2016) was an American actor, stand-up comedian, broadcaster and impressionist.
Alaskey was one of Mel Blanc's successors at the Warner Bros. Animation studio until his death. He alternated with Jeff Bergman and Greg Burson (and occasionally Billy West) in voicing Warner Bros. cartoon characters such as Bugs Bunny, Daffy Duck, Porky Pig, Sylvester, Tweety, Elmer Fudd, Yosemite Sam, Foghorn Leghorn, Pepé Le Pew, Marvin the Martian, Speedy Gonzales, Wile E. Coyote and Taz, among many others. He also voiced Plucky Duck on Tiny Toon Adventures from 1990 to 1995. Alaskey was the second actor to voice Grandpa Lou Pickles on the Nickelodeon cartoon Rugrats (taking over after David Doyle's death in 1997). He voiced Lou again in the Rugrats spin-off series All Grown Up!, as well as the Rugrats film trilogy.
