Voice actor Rob Paulsen tries his hand at improvising the voices of 12 random cartoon characters that he has never seen before. Using a similar technique he used for Yakko Warner (Animaniacs), Raphael and Donatello (Teenage Mutant Ninja Turtles), and Carl Wheezer (Jimmy Neutron), Rob brings these characters to life.<br /><br />Rob Paulsen lends his voice to 'Animaniacs' coming to Hulu later this year, and his memoir Voice Lessons is currently on sale.
